don't let them know that they're getting to you. what happend to me was the chick was callin me fat and stupid and ugly and making fun of everythin about me, and goin round sayin i have a penis even tho i'm a girl... lol. and i just went up to her and laughed. i said somethin like "you should be a comedian, you're really hilarious." and she just kept on bein mean to me and i just cracked up. i said "seriously, that's funny". then she stopped, because she knew i didn't care what she said.
