Karyn is Sarah's Friend?

Suddenly, Sarah heard a girl from behind her shout out her name. She turned around and saw Karyn Black, a tomboy girl who was friends with that loser Jon Gibson. "Sarah, there you are. I've been looking all over for you. Have you seen Jon?" asked Karyn. "Why are you *talking* to me?" Sarah asked. "Uh ... because you're my friend?" Karyn said. "Your *friend*? What planet are *you* from?" "Uh ... this one. Come on, Sarah. We've been friends for at least four years." "Ugh. I would *never* be friends with *you*. You're so ... tomboyish," she said with distaste. Karyn looked at her oddly.
