Guys, you don't really have to talk to be respected. Like me. I'm usually a nice person to everyone at my school, even if I hate them. I'll bring up their papers, share my lunch, help them with something, make them laugh about something, I don't know, but you catch my drift. I usually don't talk to 80% of the kids in my school, but when something happens to me people will say something to the person starting trouble with me.
Also, if you agree with what people say about you like, in my case, people use to call me "big lip" or say something aout my fucked up teeth in grammer school, or they would do the notorious, your mom is so ugly and stupid, and I would go, "I know right?", thus it wasn't fun anymore when they would say it.
