*Sarah and Jane are having a coffee together. Cindy walks by and says hello*
Cindy: Hey loser, how's life being the tubbiest girl in town?
Sarah: Better than having the ugliest face in town.
Cindy: Coming to Steve's party tonight, or weren't you invited?
Sarah: Actually it's Tom's party, if he'd invited you himself, you would have known!
Cindy: Oh wonderful! See you tonight girls!
*later*
Jane: I don't know how you can stand her. She's such a bitch to you.
Sarah: Yeah, but it's weird... I just dish it right back, and we seem to have sort of reached a bitchilibrium.
