Sarah is Stephanie's Friend?

Suddenly, Stephanie heard a girl from behind her shout out her name. She turned around and saw the one-and-only cheerleader bitch Sarah McMillan, dressed in her typical preppy pink outfit. "Stephanie, there you are. I've been looking all over for you. Have you seen Biff?" asked Sarah. "Why are you *talking* to me?" Stephanie asked. "Uh ... because you're my friend?" Sarah said. "Your *friend*? What planet are *you* from?" "Uh ... this one. Come on, Stephanie. We've been friends for, like, at least four years." "I would *never* be friends with you. I'm not even a prep." Sarah looked at her oddly.
