I agree with soe of what furybull was saying. a lot of people in my school act like nice people to the teachers, but in reality are assholes. this made me feel contempt for someone who was legitimately nice, but usually hung out with some of the asshole kids, until I talked to him.
p.s: be nice to everyone, regardless of how they act towards you. It's a tried and true method by yours truly. you also feel better about yourself, and you're not spending time thinking up the latest-and-greatest disses and burns
