This Troper never told her friends she had a brother (she still dislikes telling people we're related) and he didn't like telling people he was related to her, their friends overlap and occasionally they'd see them fighting and then avoiding each other for days on end and because she's a Tsundere and he's a Jerk, they jumped to the conclusion that they were dating and were in the middle of a fight. They still make jokes about us being incestuous. On the less squicky side, they used to be mistaken for twins when they were little.

My sister is roughly six years older than me and she has a 1-year old. We've recently been going on walks (to the park, to the book store) with my nephew in tow. People stop and gush over him sometimes, and we've gotten a few "Your son is so cute!" statements.

So, my twin sister and I went to seperate boy and girl schools and students would usually date each other. I never told my friends I had a twin, so one day when she walked over to my school and greeted me with a hug, my friends (and I) were appropriately squicked when one of them said, "You never told us you had a girlfriend!"

This troper has 2 brothers: one is 13 years younger, the other 4 years older. The boys look related, but she looks completely different. When she was walking with the older brother and the baby, they got dirty looks. In fact, many people didn't know this troper had an older brother. So when she hugs him or he picks her up from school, a lot of people wonder if they are dating. This has also happened with her cousin, who is closer in age. And she has also been mistaken for her little sister's mother. Or dad's much younger mistress. Being the most different in looks from the rest of the family has disadvantages. It does make for some giggles, though.

Last year, when this troper was 14, she and her gray-haired, 50-something father went to her aunt's birthday party, in a dimly lit resturant her grandparents frequented. Her 50-something mother and tween brother could not come. One of the waitresses, who we had met before but not seen often, asks me "How are the kids?" She still finds the implications disturbing.

This troper's sister was mistaken for his girlfriend at a family function (the actual girlfriend, who's '''a decade and a half older''', had a [[strike:subsequent]] previous engagement).

The scene, a nightclub in the mid 1980s. Participants - me, and my 8-years-younger 6 foot tall brother. When he was in the toilet, a man approached and asked me to dance - then asked if my '''boyfriend''' was likely to come back and tear him a new one! I had the utmost difficulty in convincing my new beau that the 'boyfriend' was my brother, who was in his teens and would n't dream of beating anyone up... But that explained why both my brother and I had been completely unsuccessful in 'pulling' that evening! (I thought the resemblance between us was un-missable - apparently not!)

That happened to me too, with my little brother. Worse, he was only thirteen at the time (I was 18).

This troper worked at a movie theater. His coworkers mistook his twin sister for a girlfriend.

Back when This Troper was in high school, This Troper, This Troper's Sister, and This Troper's Sister's Friend were speaking. This Troper's Sister's Acquaintance (who did not know This Troper) saw us talking and said "You two should totally go out." And he did not direct it at This Troper's Sister's Friend. After all three people in the original discussion pointed out the flaw simultaneously, TTSA stammered for a minute before reasserting that TT and TTS should still go out and walking away embarrassed.

This troper and his relatives all have approximately zero resemblance among themselves (with few exceptions). High school passed with very, very few people realizing that he was in fact related to the girl two years younger than him with the only other instance of their last name in the entire county. Of course, karma got this troper back-- he wound up making the same error about ''three'' other familial groups.

When this Troper was about 14 she used to go to the movies with her father quite often and apparently her father used to get a lot of dirty looks, mostly from women. They both think it's pretty funny. Her mother, on the other hand...

That happened to this Troper all the time when out in public with his then 15 year old adopted daughter. Adding to the intensity of the dirty looks were the facts that the daughter is a Filipina/Chinese (while this Troper is simon-pure Caucasian), and that she looked 15-going-on-22 or so.

This 19-year-old Troper took his then-15-year-old cousin to a talent show. Then, on the second night of it, when he went alone, one of his female friends asked if she was his girlfriend, which provoked a reaction not unlike Maya Fey's shocked sprite.

This Troper received a lot of dirty looks at 23 for taking his 14 year old cousin to the movies.

Once on a plane, a flight stewardess thought that this troper and her dad were wife and husband. She wasn't much older than maybe thirteen. Her dad was in his mid forties(admittedly as a runner and a pilot he looks good for his age, but still!) AAGH! She finds pairings with an adolescent girl and a middle aged man ''extremely'' Squicky.

Subversion: This troper looks really young -- mid-twenties, but mistakable for fifteen on a bad day. The bad days are happening less often, and the troper is getting to be really relieved about this, seeing as ze is married to a person in their forties. A door-to-door salesperson once assumed the unthinkable assumption (!) and the troper slammed the door in their face.

This troper has been mistaken for her father's wife on two or three occasions. Notably, when he attended an awards ceremony for my choir with me, and my mom had a prior engagement. We sat together and I spent ten minutes conversing politely with a woman at the same table before she turned to encompass my father as well as myself in the ensuing question and asked "Now, who is your child?" There was a moment of silence, and then, simultaneously, my father pointed to me and I raised my hand. The woman was mortified.

Frequently happens to me and my (40-years older than me) father as well. I don't know what's worse--the dirty looks from those who disapprove, or the leering looks from those who do. Additionally, I am often mistaken for both of my nephews mother. This isn't so bad with the younger (ten year old) one, as I'm 20 years older than him, with a complexion almost identical to his, so it's a reasonable assumption. But I'm only ''12 years'' older than the older one (he just turned 19, so when people make that mistake, I'm left wondering what kind of tramp they think I was to have given birth at 12, or worse yet, do I look REALLY older than my age?

This troper, lacking a birth partner at the last minute, had her father in the hospital with her. And had to keep telling doctors, midwives, anaesthetists etc that he was "MY dad, not the baby's dad".

At the birth of this European troper's third child, his wife had a female friend at the delivery, too. (Nothing extraordinary in some non-Western cultures.) However, afterwards at the maternity ward, the wife hid entirely under the blankets being utterly exhausted, while the troper held his newborn daughter in his arm and had the friend by his side. Enters the chief nurse, saying something like: "Oh, you are the grandparents."

This Troper, in order to avoid just this situation, made sure to only speak briefly and on rare occasions to his one-year-younger sister while they were at high school. Said sister ''still'' sometimes brings this up as some sort of horrible betrayal, even though This Troper has explained his reasoning several times.

Above troper has security issues.

This troper met a member of her brother's photography club who assumed they were dating. Funny considering he's gay...however, he's "straight gay" so people don't usually guess until he tells them. The person who made the mistake was mortified, but we both laughed it off.

This troper and his theater-acting brother, quite deliberately. It helped that no one's seen him act enough to know how good he is, but it doesn't help this troper to know that he's ''dating his brother''.

This troper has experienced an inversion--in middle school, when she and her boyfriend (same age, same grade) were walking the track holding hands, they were mistaken for siblings. They later admitted to seeing a resemblance.

Interesting...this troper's boyfriend once theorized (before we were actually going out) that he and I were at-least-half-siblings, as we may as well share a brain, we're so close. FridgeLogic made me ask about the fact that we're only nine months apart (I was born first), but it didn't deter him.

Once, this troper's aunt and uncle were mistaken for the parents of the troper's mother. Ouch.

This troper vaguely knows a little boy who lives in town. He once informed her that her mother had come to take her home, but she knew her mom wouldn't come pick her up for a few more hours. As it turned out, said mother was her sister, who is six years older than her. She gently informed him that it was her older sister. Next week, the boy asked, "is that girl your mom?" while pointing to her other sister, who is five years older than her.

At a Family Reunion this Troper was asked if he was his mother's brother! Though the fact that by this point I was a little bit taller than my mother and standing right next to her at the time ''might'' have had something to do with it.

At this troper's work place, people at my work confuse my mom for a older sister. !

This troper's ex-classmate's younger sister was once mistaken for her daughter -- although, to be fair, at that point she was 18-19 and her sister was a toddler. Her mother was also mistaken to be her older sister once.

This troper's mother (late forties) was mistaken for her brother's (early forties) mother. Ouch.

This troper used to go to the gym with his mother who is thirty years older. One day, she was asked if he was her brother. Similarly, since I bear little resemblance to my siblings, people rarely guess that we're related unless we tell them, and because of my bright red hair, people seem to automatically assume any red-haired girl I happen to be conversing with at a given time is my sister. Or my girlfriend.

As opposed to taking a forty-five minute bus ride home, this troper would oftentimes meet her father at work and ride home with him. One day, after hugging him hello, I left to visit some ex-co-workers, having worked at the adjoining location last summer. After I left, one of his employees, after eying him suspiciously for several minutes, asked him: "So...why was that white girl hugging you?" He knew my Dad was married (to a fellow Puerto Rican, by the way) and had several children, and couldn't figure out what business he would have hugging a girl that young and with no apparent relation to him aside from...well, the obvious. After my father informed him that "That's my daughter, you motherfucker!" his response was, "But she's so white!" Ironically enough, my mother's family is also fairly dark. It's my ''dad's'' side I take after, seeing as how they're part French.

While my sister and myself haven't been mistaken as anything other than sisters, our birth order has been confused- with the taller, more mature-looking girl being called the ''younger'' sister. We're three years and 4 cm apart.

This (female) troper has a wonderfully witty HotShounenMom, whom she would totally jump were the good lady male, nineteen years younger and (by grace of the first two points) not her Mum. She has also heard stories about and seen yearbook pictures of her mother's cute, geeky high school boyfriend. With whom said mother had a son, who was then put up for adoption. This means that there is a guy out there, only a few years older than her, who is clever, handsome... and her brother. The worst part is that there's no way to ask the necessary question without it leading to awkwardness: "Oooh, I like your style. Say, are you adopted and do you have a grey teddy bear as a token of your birth mother? You do? Oh, yay, I found my brother... who is exactly my type... aghaghaghbleah!" ''There's'' a josei manga plotline for ya.

My sister's a year older than me. My other sister's 12 years younger than me. People looked when we were the three together. *nod* (Started when I was 16 or so, btw)

Oh, and people have always commented on how well my older sister and I get along. And then take note of the hand-holding-thing. Stupid people.

My neighbors, whom I don't even know, seem convinced that my mother and I are a lesbian couple. I think it's hilarious. My mother is less amused.

This troper's sister is about 12 years younger than him. Sometimes he gets mistaken for her father. He's still slightly perplexed by this. (Thankfully, this is happening less often nowadays.)

I'm only 12 years older than I my oldest nephew and I've been mistaken for his mother ever since he was a baby. Either I look a ''hell'' of a lot older than I am, or these idiots think I was a twelve-year old tramp.

Also, he was recently (as of October 2009) mistaken for his aunt's brother. Even more perplexing, given that said aunt is over twice his age.

This (male) troper was often mistaken for my dads wife, apparently i looked rather girlish at 14 or so (and both me and my dad have rather high pitched voices). And I was some pushing my litle sisters stroller I guess. Now that I'm 6'3'' and have a beard, people just think we're siblings. I think it's 'cause he wears T-shirts or something?.

This (24 year old) Troper and his 11 year old niece have been mistaken for this. Now granted, I look closer to 16/17 than 24, and she is always very affectionate with me, but come on... Is that really what it looks like?

Mistaken for my Dad, especially on the phone or next to my mom. My friends don't see it, but they haven't met my dad. On Halloween, people kept thinking that my sister and cousins were my kids. I'm 16, and he around 50-60. I gotta work hard to make that connection.

My sister and I were constantly assumed to be ''married'', especially whenever we flew anywhere together (we attended the same college so it happened alot), I guess the same last names make them assume marriage. Of course she takes after Mom being a round-faced blond blue-eyed bombshell, while I take after Dad being narrow-faced, dark, hazel-eyed. We both have Mom's nose though (every one of my siblings does), so you think people might notice that. I find it incredibly amusing, and I love to take advantage of any goodies offered because of a mistake like this, but it freaks my sister out. When she got married she assumed it would be over now that she has a different last name, but just last year an airline attendant assumed that she was my wife and my nephew was our child. Her husband was assumed to be a sibling... he thought is was funny too. I guess it must be the BelligerentSexualTension vibes or something.

My mother on the other hand is commonly mistaken for my older sister- dating all the way back to when I was ''one month old'' and my mother (21 years old) answered the door with me in her arms and the door-to-door salesman ask to speak to our parents!

Happens an awful lot when I'm walking around town/ eating out with my brother.

Please rephrase that.

In the 70's this troper's mother and grandparents were driving from Washington to Minnesota. They ran out of money halfway, so my mother and grandfather visited all the local churches looking for handouts. My mother was 14 at the time, her father was 40 years older than her. A preacher took her aside and told her he was appalled that her "husband" was so much older, and asked if she needed help getting away from him.

This Troper's and his younger sister are very close, and with her active social life, he is often called upon to take her places when their parents are too busy. He also shows up at her fencing meets as often as possible, as he also fenced in high school (and was the inspiration for his younger sister to take it up when she got to high school). It was only a matter of time before one of the other fencers mistook this troper for her boyfriend. (Troper was 18 at the time; sister was 14. However, all guesses as to this troper's age have consistently come up two years short for the past decade or so, and he also graduated high school two years early, so the freshmen in this troper's senior year were seniors in the sister's freshman year; it was a sophomore that asked me if I was her boyfriend. Hopefully the days of being Older Than I Look are over, as I've finally grown a decent beard.)

This (21 year old, bearded) troper gets uncountable dirty looks when hanging out with his (15 year old) Neice - ok she's a Neice by Marriage so looks totally different, but still...{{squick}}.

This troper and his androgynous, theater-acting brother were often seen to be a couple by other people. This is comparatively better compared to how they were previously seen as brother and sister, though the frequency of these assumptions happening increased since this troper took his brother out for high school senior prom.

At fifteen, {{Gecko}} was mistaken for her eleven-year-old sister's mother, and a year later, for her 47-year-old father's ''wife''.

This troper is only 2 years older than her brother and can't be seen in public with him without being mistaken for his girlfriend. This despite the fact that we bicker constantly like, well, like brother and sister.

One year, this Troper's brother greeted my aunt visiting from across Canada. His welcome? "Hi Grams! Where's Auntie Bobbie?" He never actually figured out that it was an insult for a couple years.

Inverted with this troper-people keep assuming her girlfriend is her sister, despite the only part of their appearance they share is pale skin. How people can think a woman whose parents came to the US from China is related to the woman with blonde hair and blue eyes is beyond either of them.

This gay troper and his straight brother tend to be mistaken for a couple. We both find it hilarious.

This LDS troper served as a full-time missionary in the 1999-2001 period, and in that time, troper's sister gave birth. Nephew was less that one year old when troper was released, and the very first Sunday attending church back home, more than half of the membership (bishop included) assumed that troper was actually the father. Took a lot of time and effort to clear up things, considering that some people went so far as building whole stories about troper working far away, divorce... even incest ¬¬. Justified (in part) due to the fact that in said period, most of the old time members moved out of the city (bishop included) or plainly stopped attending church, so the ward was filled with new people and new bishop.

It's been inverted in this troper's case, as one time he was mistaken for his then-girlfriend's brother. I guess similar complexions + glasses = siblings.

Due to this troper's early-learnt habit of calling his parents by their names, evidently a lot of people have mistaken my mother to be my sister instead.

This troper, her sister, and sister's boyfriend (now husband) ran into her old high school friends at a concert once. Before I could introduce them, one friend assumed they were my sister and my brother. I jumped to correct him, and he sighed in relief. "I ''thought'' your brother and sister were being awfully touchy-feely..." Oddly enough, he guessed closer than most, who still assume my brother-in-law is my brother and I'm lucky to get along with his wife so well. Huh.

This troper once went to a party with her two-years-older, two-centimetres-shorter sister. Neither of us knew anyone there terribly well, and ended up clinging to each other most of the time. The host was asked by one of her friends if we were twins, and by another if we were dating. We found it hilarious. This troper has also been asked if she is her mother's little sister.

This troper was once in high school with a girlfriend that had a similar build and hair and eye color. His sister, also at the school, had a different hair color, eye color and build. this one found itself having problems with this trope, and being accused of BrotherSisterIncest.

This troper was once asked by a work colleague 'who's the woman with the blue car who picks you up outside work?'. He played them along for a few minutes before revealing that 'that was no woman, that was my mother'

This troper and her sister have been accused of a lesbian version of this. They've played it for laughs at anime conventions before, even though they are identical, which makes it ridiculous when it happens in supermarkets and other public areas.

This Troper has a particularily stupid semi-bully at his school. Said bully confused my little sister for my girlfriend (especially odd since I look way older than I actually am and she looks way younger) and later on, the same bully confused my BIG sister for my girlfriend while we were going to the shops. The stupid part is, he never actually saw me interact with them in any way. He just saw me walking with a girl and automatically assumed that we must be dating. What the hell?

Are you sure he's not just bullying you because he envies your success with women?

ThisTroper and his sister look totally unalike, are very buddy-buddy and spend a lot of time in bars together. You know the rest.

This troper has gotten this for every single member of her family except her mother. Her father looks like her husband (ew), her sisters are pretty clingy, and we all look nothing alike. (My dad's a tall, Clark Kent-looking guy in a sharp suit, my sisters are both leggy, cute blondes in school uniforms. I'm dark-haired, deathly pale, look like I just crawled off of Elba, and am far more comfortable in jeans. Therefore, I apparently translate to either twenty-years-his-junior trophy wife, or junior lesbian.)

Happens to this troper a lot whenever someone sees a photo of her as a young child. She's mistaken for her ''father''. And viceversa.

This troper has experienced different forms of this with different family members. He is now 26. He has been mistaken at various times for dating or even *being married* to his own mother, being the younger brother of his own father, but more often than not is mistaken for being romantically involved with (boyfriend/fiance/husband of) his 1-year-older sister (who is incredibly squicked by the whole idea to almost comic proportions). He's even been mistaken on one occasion (by someone thinking he was much *older*) for his older sister's uncle....or dad.

This troper has been confused for his brother's girlfriend. That's when you know it's time to cut your hair.

This troper's best friend is commonly mistaken for her sister. Conversely, she looks nothing like her three-years-younger brother (who is nearly six inches taller than her), so people keep asking her if he is her boyfriend. This troper is lesbian. This troper has actually begun wondering if she is somehow (impossibly) adopted, since she looks nothing like anyone in her family.

This troper's step-father has been mistaken for her grandfather, her grandfather mistaken for her father, her mother mistaken for her sister, her half-sisters for her daughters (once by one of her former teachers), and her younger brother for both her husband and her older brother. None of this is inexplicable if you realise she, her mother and grandfather are OlderThanTheyLook, her step-father YoungerThanTheyLook, the half-sisters are between 16 and 20 years her junior, and she and her brother are the only ones with their surname who live at their address and this troper prefers to be called Ms.

This troper mixes up his mom and older sister all the time, usually because he's seeing one of them in a dimly lit room or from the back. They are nearly the same height (mom is five foot even, sister is five foot one), have a similar haircut, they even walk in the same way! Yesterday when this troper mistook the sister for the mother, the sister said "Mom doesn't wear glasses." ... oh wow.

My ego took quite the blow when, on our first meeting, the mother of my sister's boyfriend thought I was sis' mom. It was slightly restored after sis took me aside and explained said boyfriend's mother can't see well and had forgotten her glasses on top of being very nervous, but still. The more usual example of this trope is people mistaking us for twins... despite her being three years older, more mature looking and having a completely different body type.

This troper, her sister, and this troper's best friend often hang out in a group. People who don't know us but know that two of us are siblings often mistake this troper and her best friend for the siblings. Since the two of us have brown hair and this troper's sister has blonde hair, it's halfway understandable, except for the fact that aside from that, her sister and she look very alike and her best friend really doesn't look that similar.

This troper recalls an amusing incident when someone though she and her mum were both her dad's daughters. This troper was 16, and both her parents were late-forties (although they do look fairly similar). A friend of hers possibly topped that story, complaining that she and her mother are ''frequently'' mistaken for a lesbian couple.

This troper has been heard many people ask if her Dad was her husband. Similarily, lots of people mistake this troper and her Mom as sisters. This troper is only a teenager, but gets asked out by many people who think she's in her mid-twenties. Even worse, this troper's younger, 13 year old sister is often mistaken for the older one.

This troper had 2 high school friends that were fraternal twins of opposite gender, seeing as they were always hanging out together at school between classes its probably not surprising that a number of students (and teachers for that matter) mistook them for a couple if they didn't already know they were related. They complained about the squickiness of these misjudgments constantly.

This used to and still happens constantly to This Troper and her aunt, uncle, and cousin, (when we all aren't mistaken for siblings) since we're really close.

When I was younger; my (now deceased) nine year older cousin who I was very close to and me, were often mistaken as a couple by everyone whenever we went out together. My schoolmates, my teachers, his friends, his former teachers, and once even by his own mother. Considering how androgynous I was as a kid, I've also been mistaken for his boyfriend.

Our aunt (who like everyone from my mothers side looks much younger than she is) was also often mistaken for his girlfriend.

When my grandmother was hospitalized the nurse mistook them (my aunt and cousin) for a couple, and me as their kid.

I'm also often mistaken for my uncle's girlfriend - and sometimes boyfriend - from time to time.

My uncle and my cousin have also been mistaken for a gay couple.

These days people mistake me and my aunt for a lesbian couple, whenever we go out together. Look she may be hot, but it's a major {{Squick}} for me.

This troper is only a year older than his sister, and we look nothing alike. Naturally, this happens a lot. People don't give us looks anymore, though, mostly because we are actually old enough to date.

I live with my parents during the summer, because my college doesn't have a summer program and I haven't officially moved out yet. The drive back was too far to complete in one day, so we stayed over at a hotel rather than drive through the night. At least two staff members assumed that we were on a honeymoon. This is made worse by the fact, while I ''am'' old enough to date, you can't tell that by looking at me.

This troper recalls a funny scene at a high school band competition. One of my friends had just been visited by his college-age sister, who had hugged him. As she left, one of the freshmen asked him if that was his girlfriend. There were a few squicked/confused looks, but the friend in question just burst out laughing.

This troper's twelve year old brother (who is seriously 5'11" (eight inches taller than this troper) and looks like he's fifteen or sixteen, while at the same time looking nothing like this troper) was once mistaken for this troper's boyfriend when she accompanied him to a movie we both wanted to see. This troper was not amused. Also, in an inversion of this, this troper's best friend was once mistaken for her sister, despite the fact that we look nothing alike.

When this troper broke both one of his arms and a leg playing football, his twin sister had to help him out a lot during school. With the way she helped me, people thought we made a cute couple. *{{Squick}}

This 23-year-old Troper once took her 15-year-old brother to Six Flags. While on a roller coaster that ended in tunnel, the people sitting behind us asked if us "lovebirds" were going to make out in the tunnel. Cue my brother gagging, and me turning around with a bemused grin and saying "Ah, that would be rather gross since he's my brother." The questioner flushed mightily and exited the ride quickly once we came to a stop. This troper has also been mistaken as the mother for both her younger brothers (17 and 15 respectively). I mean, yeesh, I only would've had to have been 6 at the time I had the first one, right? I mean, theoretically its possible, but still. . .

This troper still has people mistake him for his brother. It may be because we look alike, or our names sound identical, but it still happens.

This troper, on account of looking five years older then he is, has occasionally been thought of being his (eleven years younger) sister's father. And married to his mom.

Local bully assumed my younger sister was my girlfriend. We basically responded with "lolno". Local bully thought my OLDER sister was my girlfriend in a completely unrelated incident. I'm still wondering why the hell this bully, who keeps making fun of me for being a nerd and a social outcast would ever think I would get a girlfriend.

This troper had a moment where a very obviously drunk redneck on the street commented on how my half-sister (who is a baby and looks nothing like me) looks so much like her mother. Only a 14 year old me and my dad were with the baby. My dads incredibly sarcastic comment was "yeah, I like them young and related to me".

This troper, her sisters (one that looks obviously older and one obviously younger), and her mother all missed their flight home once. They went to the help desk and got transfer slips to get on the next flight out. Then the sisters went to a gate to confirm their seating arrangements, and their mother went to the bathroom. When asked for the tickets from the flight they missed, this troper remembered that her mother had them, and told the attendant at the gate as much. She then went to go get the tickets. Halfway there, she remembered she had the transfer slips with her, so she returned and gave them to the attendent. The same attendent who she had spoken to only seconds before. Who then remarked, "You're the mom, right?" '''WHAT.'''

this troper was going shopping with her oldest and middle nieces 5 years ago when she got asked if they were her kids. this troper was 12 when her oldest niece was born and it's only her youngest niece that she could be old enough to be the mother of. it was quite the change from being mistaken for being their older sister (or occasionally my older brother's oldest daughter).

This troper used this to her advantage. After being constantly stalked by a creepy older man on her train to college, she decided to sit next to and hold hands with her 50-something Dad who took the same train. Although her Dad was none the wiser, the creepy stalker completely got the message.

This troper (19) and her cousin (20, also female) took another cousin (4) out to get ice cream one day. A passing stranger made some very awkward comments; it seems she mistook us for a lesbian couple with an adopted son. A squicky and utterly baffling conclusion.

Variation. I was babysitting a kid and we were about to watch a live show at a small theater. Show hasn't started yet, and a middle-aged woman sits down next to her. She assumes that the kid is my ''daughter''. My brain effectively died on me, because I was seventeen, the kid ''eight''.

Less {{Squick}}y example by this troper. She was once mistaken for the younger sister of one of her own little sister's classmates. Okay, he is taller than her, but she's three years older than him!

So I'm taking my mom out to lunch for Mother's Day, and the waiter says something about how "your girlfriend's pretty cute." Judging by the expression on his face, telling him who she was made him assume ''something worse''. Fortunately, she finally looks old enough that that shouldn't happen again.

At this troper's uncle's wedding reception, this troper and his cousin saw a rather attractive girl who was about our age. The girl turned out to be the cousin's cousin.

This troper once read to his church's congregation from the Bible, and many in the audience were surprised because they thought that the one doing the reading was this troper's father (to be fair, we do look similar).

This troper, while waiting with her three younger sisters for their mother to come out of the Walmart restroom, was mistaken for their mother by another shopper. To be fair, this troper was yelling at them, telling them to sit down and shut up, or they'd be in so much trouble when we got home, and we all look alike, with the exact same shade of dark hair and similar builds. And this troper has been told that she looks most like the mother.

This troper, being basically a lesser version of Sheldon from ''TheBigBangTheory'', is extremely bad at figuring out humans and relationships. He has managed to ask a brother/sister pair if they were a couple, then the next time he asked a couple if they were siblings.

This troper's older sister and dad were at a store once and were mistaken to be dating by our dad's coworker. In a modified version, my best friend and I are continually mistaken for identical twins; what makes this even worse is that my best friend HAD a twin sister who died not long after birth.

I'm sure it happens all the time to other people too, but I got this reaction from a co-worker one day after school (thankfully we were on good enough terms to immediately laugh it off): #QUOTE#Co-Worker: Aw, you two make such a cute couple! #QUOTE#Me: Um, hi, let me introduce you. This is my little sister.

And I've also had a store clerk mistaking my 9 year-old cousin for my daughter. Technically, that would be possible (though it'd involve squicky ages all around), but since despite our age difference we're still on the same family-generation level and we both like the same things (anime, video games and so on), she reacted much more strongly with "ack, NO, he's my ''cousin'', sheesh!" than I did.

This troper has a pair of friends who have the same hair color (though different styles), same eye color, same skin tone, who live in an apartment together, who share a secret writing system between them, who share the same circle of friends, and share tastes in food, alcohol, music and women. They constantly, CONSTANTLY get mistaken by strangers for being boyfriend and girlfriend, or, worse, husband and wife, despite being fraternal twins and, if you didn't get that before, the sister being lesbian.

Let's see, one of my friends who looks like me was once mistook for my twin. I was once asking somebody if she had seen a friend of mine, and somebody mistook me for her daughter. Et cetera, et cetera.

Back when I was seventeen and still lived with my mother in an apartment buildning, I once met our upstairs neighbour in the laundry room. He took one look at my HUGE pile of laundry and casually asked if I had many children. I'm not sure whether he didn't recognise me (higly unlikely, since it was a rather small buildning and we had been living there for over a year. Plus, he had talked to my mother several times with me present) or whether he thought that I was older than I looked and was in a lesbian relationship with a woman in her forties.

At my family's big 4th of July party, all the kids hang out in the pool and yard while the adults chill on the patio. All my young cousins and my friends had been successfully introduced and were getting along well when we stopped to eat. One of my newer friends pointed at two of the kids we'd been hanging out with: a lanky boy with black hair and ice-blue eyes and the petite, brown-haired, brown-eyed girl sitting on his lap. They were draped over each other, almost cuddling, and sharing the same plate of food. My friend asked me, "Are they dating?" I cocked a brow and answered, "No, they're both my cousins. They're just like that." She studied them, then replied dubiously, "Are you sure?"

This lurker and her sister often get told by older relatives we look like our mother and aunty when they were younger and are often called by their names. Also, due to a mixture of genetics, glasses and gender confusing haircuts (as well as attending a single sex school) we are sometimes asked if we're dating. This happens a lot when we're out with our younger brother too. It's rather annoying.

This troper's Grandfather always looked very young for his age - Whenever he went to a disco with 25, they wouldn't believe he's already 16. He and this troper's mom used to go to the theather a lot and he got frequently mistaken for her boyfriend. This troper herself looks a little older than she is thanks to her F-Cup-Breasts and got mistaken for her one-year-old sister's mother once...

Inversion: People frequenty assume that my brother and his girlfriend are siblings. Lately, he has taken to calling her "sis" because of it.

This Troper's older brother is extremely insecure about this. I find it hysterical and am not at all bothered by by it because, well, we don't look related at all. I look like our father (black hair, grey-blue eyes, pale) and he looks like our mother (red hair, hazel eyes, tans well, has freckles, and has much more soft, rounded facial features). Honestly I don't get what the big deal is over people continually assuming we're dating; if this is such a problem, maybe he shouldn't insist on wrapping an arm around me when we cross the street. (It was cute when I was three and he was seven, but now it's annoying as hell.)

This troper has six or so much younger full cousins, a much younger sister who shares no family resemblance to the troper (''possibly'' aside from being large for her age) but is said to look extremely similar to their mother, a slightly older half-cousin, and a slightly younger step-cousin. After the troper's mother brought a group photo to the office, it was widely assumed that the troper and the step-cousin were "the" (the word "the" ''was'' used) full siblings. The bleached hair (on the step-cousin, not the troper) probably had a little to do with it, but considering ''the troper's younger sister visited the office every so often'' (and the troper visited rather often, and was at least vaguely familiar to the office workers), they really didn't have much of an excuse.

On vacation, this troper's sister (28 at the time) was mistaken for her dad's (56 at the time) wife, while her (troper's) ''actual'' mother (42 at the time, looks late 20s-early 30s) was mistaken for his daughter. Also, my mother is entirely convinced that people who don't know us think that she and TT (14) are lesbians. Even ''I'' am squicked by the thought of this.

This troper has no less then four sisters of a close enough age to be mistaken. As you may have guessed this happens a lot. The worst is when this troper goes to the local mall with his sister, and her child. The comments we gto were very disturbing to say the least (it does not help that we are step-siblings and thus do not look a like). The only thing worse is that sometimes this troper takes his little sister to movies. The looks we get. Oh dear.

This troper has only ever had strangers mistake his (twin) sister for a girlfriend, but it happens REALLY frequently. Is it weird that this troper takes it as a compliment? (Is it weird that t.t. recognises his sister would be out of his league?)

After a party this troper attended with her two-years-older sister, the host informed them that two of her friends had approached her wanting clarification on their relationship-- one asked if they were dating. The other asked if they were twins.

This Troper's mother has admitted to him that she and her twin brother/my uncle have been mistaken for a married couple. Just...what the hell.

Happened to this troper when visiting a winery; both her and her father were offered a sample of wine. You can imagine the look on the salesperson's face when this troper turned down the sample and declared herself underage.

This troper's boyfriend is a subversion: all his first and second cousins are much older than he is; the ones his age are third cousin or beyond and thus "legally" fair game. So she knows for a fact that if he's being a little too friendly to another attractive young lady, it's exactly what it looks like.

This troper got this. She and her brother are very close, and went to and outdoor education thing as camp counselors. Despite being more that just "like" brother and sister, several of the kids and even other counselors were under the impression that they either were a couple or would make a good one. Probably the hugging in that environment.

She also had a separate instance with her mother. In an interesting case, her father actually ''was'' there and we were clearly a group--the party was primarily gay, which is probably what led the guy to make the same-sex couple assumption. The guy's words werekeep in mind that this troper's father is fairly average-size, clean-shaven, and straight as can be: #QUOTE#''I understand why they're together, but what's in it for the bear?''

I get this frequently with my sisters, who are four and five years younger than I am. The first time, it {{squick}}ed me to hell, but now I just find it funny.

Less frequently, with my mom. A friend once ran into me while my mom and I were at the local farmer's market, and he said (away from my mother's hearing) that there was ''no way'' that she was my mom. #QUOTE#'''Friend:''' You're, what? Twenty-one? Twenty-two? That woman is thirty-five, tops. #QUOTE#'''Me:''' She's my mother, and she's fifty. #QUOTE#'''Friend''': Get. The fuck. Out.

This troper frequently is mistaken for about 5 years older than her actual age of 21, but a particularly embarrassing incident happened at a fundraiser for a gay rights organization that I attended with '''my mom''', who is in her late 50s. Apparently people thought that we were '''a couple''' and had some sort of MayDecemberRomance thing going on. Now I actually ''am'' gay, but my mother is definitely not, and we're definitely not together.

Non-Squickily. People used to think me and my 2 year younger sister were twins when we were 5/6. Now the only problem is she looks older then me so she's the adult and I'm the teenager now.

This troper and his sister deliberately don't walk down the street together because he has been mistaken for her boyfriend more times than he cares to admit. There is a year and quarter difference between our ages, which makes this slightly worrying. This became a bit less of a problem when my parent's split up (my sister decided to stay with my mum for teenage events, while I stayed with my dad because there was no point in getting my hopes up at the time), but recently, she held a party (not an alcoholic one: my mum doesn't drink) and her friends didn't believe I was her brother at first.

This Troper used to get mistaken as his cousin's son, since she was much older then me and baby sat me as favors for my Mom.

A few years ago when I was showing a funny picture of my mother in photography class someone asked if she was my girlfriend; my response was literally "F*** NO!" Everyone, including the teacher, thought this was ''hilarious''.-koolkame

This happens to this Troper quite often. My moms mother gets mistaken for her mother a lot. Much older cousin was once mistaken for her brother when we were at the fair. Her sister and her look nothing alike, her sister is quite loud and tends to say perverted things loudly as well, which can lead people to get the wrong idea, plus she hands all over me all the dang time! Then, the big two. I went to the mall with my sister and 3 of my cousins (all siblings, 1 girl, 2 boys). We all separated, mixed-and-matched for a while and one time I was with my older cousin (by a year), whom he and I look nothing alike, and someone said we looked so cute together when he was buying something at the shop. But we brushed it off because at that point it was awkward to talk about as we both had crushes on each other. So later, I ended up with my younger cousin (by two years) and we look a little more like and were mistaken once as siblings back when my skin tone was darker. However, this time, not so much. He wanted to go to the same shop, the girl saw this and since I have a tendency to hang all over people, like then, she thought I was cheating on my boyfriend wit this guy and confronted me about it. In the end I was like "They're both my cousins, you crazy-ass!" and she said "You're dating you're cousins you sick freak?!", meanwhile my cousin hung his head in shame.

This happens constantly with this Troper and her older brother (By 4 years), the fact that he took his looks after our father (Brown eyes, blond hair), and I took after our mother (Red hair, green eyes) doesn’t help matters. The fact that we’re very affectionate doesn’t help either. Almost everybody who sees us together and doesn’t know we’re related assumes we are together. A costant joke betwwen our circle of friends is insinuate we're incestuous and present us as a couple to people who don't know us.

This troper is short and dark-haired. Her younger brother is tall and blonde. One time when they were out together, a man called out to a "young couple". Both the troper and her brother looked around confusedly.

This troper and his sister rarely stay in the same room for longer than a minute (it doesn't help that we look very different from each other and she doesn't like mentioning me (the feeling, unluckily for her, is not mutual: I won't bring her up frequently in casual conversation, but I'm generally happy to talk about her because, well, she's my sister and I will always look out for her). Needless to say, when one of her friends (who hadn't met me yet) went to my mum's house to find me sitting on the sofa, listening to music and reading a book with my sister in the same room, she was understandably confused. The fact I act more like a boyfriend than a brother to her does not help matters.

I get this so many times. Been mistaken for my sibling's mother, my ''friend's'' mother (who is only a year younger and a few centimetres taller than me!), my father's wife (ick), my mother's sister, my mother's professional stylist.. The list goes on.

It's mostly because of YoungerThanTheyLook. I have it bad, because I am rather tall and busty. At the age of 12 I was mistaken for 23. Yikes.

This Troper and his brother were both in a Gay-Straight group in high school. Despite having the same last name and looking similar, the fact that we argued a lot and he road home with me daily apparently was enough to be mistaken for a couple.

This 19-year-old troper has been mistaken for her father's much-younger girlfriend a lot when they go to the ice cream parlor in the evenings. Two of her friends - who have absolutely no blood-tie - keep being mistaken for twin sisters despite not even having the same hair color, as a flabbergasting inversion.

My cousin and my sister got this once, with a sweet old lady assuming the two were dating. My sister was very, very quick to set her straight!

This Troper has been mistaken for Several things over the years. When I was with my mother buying a Dachshund, I was asked if I was her Husband (she's about Thirty years older than me). Later, when I was getting My photo taken for the Senior Yearbook, the Photographer thought My younger sister was my girlfriend (She's Three years younger than me). People have also assumed my Younger Brother was my Son on more than one occasion (He's six years younger than me). Doesn't help that I'm Younger than I look.

This gay troper and his female ex-best friend were asked if we were siblings/dating several times; of course the fact that we said we had the same mind (both smart, schizophrenic, bi-polar, and PerkyGoth) may have not helped.

A few years back, after being out late at a halloween carnival, me and my cousin's went to a tim hortons, and sat in a 4 person booth, me and a female cousin on one side, and said cousins two siblings, one male and female, on the other side...some drunk guy asked if we were dating based solely on the fact that we were sitting next to each other

My sister is 4 years younger than I am, and when we're alone, I've been mistaken for her mother. To be fair, she could pass for 11, not 15, and I could pass for 22-23, not 19 ... But even then you only have a difference of about 12 years. At the ''very most''. Is that ''really'' what it looks like to some people?

Have I got a story. My sister was going to some party about ten minutes by bike away with her boyfriend. Her boyfriend said he'd be late, and my sister, despite being 18 (legal driving age where I live) didn't have a car yet. Seeing as it was only a ten minute bike ride, I offered to take her there. Now keep in mind, my sister is 18, and I'm 17. I'm one head taller and I had a bit of stubble going on because I'd been lazy about shaving. So we get there, my sister rings the doorbell, I'm lighting a cigarette before I say my goodbyes. Door goes open and the girl who opened it says "No smoking in here!". Before I can explain that I'm not even coming in, she turns to my sister and goes "Wow, [name], I didn't know your boyfriend was so much older than you". She apparently thought I was like 21 or something...and just then her boyfriend turned up. Hurried explaining ensued.

This troper has had pretty much every possible version of this happen to her. People have assumed she and her boyfriend were siblings, she and her brother were lovers, and that her stepdad was her actual dad.

My brother and I have been mistaken for a couple on more occasions than I care to remember by strangers, but the ultimate squicky moment came when my uncle, who I hadn't seen for several years, thought I was my brother's girlfriend.

This trooper's father would go out and about with his wife, sister, and young nephew while his brother-in-law was at work. People thought his nephew was his son, his sister was his wife, and his wife was his sister, even though he looked like his 'wife' and looked nothing like his 'sister'
