This Troper was one back in elementary school. I didn't really suck up to the teachers, but I would go around lecturing the other kids about the rules as though I had some kind of authority over them. At one point, a teacher had to tell me to stop doing this. God, I must have been annoying.

I am this 100%. I don't even mean to. I was just mature as a kid and preferred to have conversations with adults than my silly little peer group. To be specific, I've known my choir director for forever (we carpooled), so she's sort of my adopted aunt. We're extremely similar, actually, so I usually find myself in the choir room after school just helping out. Because of this, we're constantly chatting up in class. I even got her a cake for her birthday. God, I will miss that woman when I'm in college.

I have always been one (and still are) because I'm always participating in school, and my behavior is not as bad as my classmate's. The only exception might be my current English teacher, as he doesn't know anything of English and I'm in fact explaining my classmates what he said.

Two examples here. The first one is my friend, who used to go out of his way to suck up to teachers (he's better now) and got picked on relentlessly for it. To be fair, he had it coming...he was (and is) a keeno. The second example is me. I don't go out of my way to please teachers, but I work hard and I participate in class a lot. I also have a halfway decent reputation as smart and hard-working, so they don't exactly hate me.

This troper, absolutely. Well, minus the tattling, though that was more because I never found out about stuff. It started in elementary school, due to being really smart. In middle school, I used the teachers as a defense against bullies. In high school, I achieved what must be the apotheosis of the Teacher's Pet:

Rather than tattling on my fellow students, I would openly rebuke them when they misbehaved. There was one teacher who, for whatever reason, always had trouble controlling his class. At one point, some students made a Bingo! game out of their own antics, with one item being "[This Troper] gets mad at us". In another class, the students managed to drive the English teacher to tears - and out of the class. A few other students and I immediately took over via Death Glares and resumed the class reading of ''RomeoAndJuliet''.

My teachers, being generally awesome, accepted that given my passion for learning, I sometimes knew more than they did about a subject. In my senior year of high school, my physics teacher frequently said "[This Troper], why don't you explain this concept?" I probably taught about a third of the material. Unusually, this actually won me a lot of respect from my classmates.
