Many identical twins do this to keep from being seen as a HiveMind, and are often contemptuous of the idea. This troper and her twin are an example: While both of us are quite smart, I am definitely more serious and quiet, while my sister is cheery and talkative. Physically, we haven't had the same hairstyle or clothes since middle school. And people STILL mixed us up in high school.

God, I know that feeling. I had longer hair and wiry build, he was stockier and either buzz cut or flat-top hair, both of us dressed completely different, and there were whole months when we were never seen together at school. And yet there was often someone who would come up to either of us and hold a whole conversation as if we were the other brother.

This troper has a twin who is so opposite in looks and personality that they tend to be mistaken for boyfriend and girlfriend, not siblings.

This troper went to high school with a pair of identical twins that were worlds away in personality, though they did have a few similar interests (videogames, card games like Magic, and the like). One twin was rather pretentious, enjoyed Latin, had a sophisticated vocabulary and was definitely more tightly wound, while the other twin was a bit more BookDumb, loved to just hang out and have a good time, and was more hyperactive.

This Troper and his twin tried to invoke this around junior high, just for some sense of personal identity. This didn't stop everyone from ''always'' referring to us in the plural, but it was an improvement over the CreepyTwins we were before. We mellowed out of this too, and now we're really only as different as any two other people who may or may not be related; aside from the genes, of course.

This girl and her younger sister, although we are not twins, are completely different. While I am tall, light brown haired, quiet and shy, my sister is short, dark haired, noisy and tough.

This troper and his younger (not twin) brother, to the point of me being born at night during a new moon, and him born during the day before a full moon. There's almost no similarity between us at all: not in appearance, interests, or personality.

this troper and twin count. one of us is male, blond, blue eyed, tan, skinny, about 6 foot, a fast runner, quick with fists( but not words) good with science not so good with animals, and is bad at math. the other is: female, has dark curly hair, green-gray eyes, paler than paper, a little heavy, about...5 foot, can't run to save her life, quick with words( not with fists until she gets really steamed) bad at science, great with animals(despite being terrified of them) and terrible at math.

This troper and her sister, who is two years younger. I'm short, pale, and red-haired, shy and introverted, more artistic (being a writer and all), and hopeless at math. She's taller, tan, brunette, outgoing, and prefers math and science. We were seldom seen together in high school, so very few people knew we were even sisters. Those who knew thought we were stepsisters, or that one of us was adopted, at least at first.
