7:00 P.M.

Charlize scribbled furiously in her multivariable calculus notebook, a brilliant smile spreading across her face as she solved the triple integration problems at lightning speed. Math was her favorite subject; there was absolutely no question about it. Something about solving problems had always appealed to her.

The door slammed behind her, momentarily breaking her focus. Charlize turned around in her chair, observing her roommate Ariana waltzing into the room. The Brazilian girl carried a pair of stilettos in one hand and her cell phone in the other.

"Hey Char! You headed to the big lacrosse game tonight?" Ariana asked as she headed directly for her closet.

"Nah. I've got a date with my math homework," Charlize replied. She didn't really understand the appeal of watching a bunch of sweaty guys chase a ball across the field.

"Girl, it's senior year. You need to live a little," Ariana chastised. "Oh, and I'm going to be back pretty late. There's a party after the game."

Charlize rolled her eyes in response.

Honestly, for two girls who were so alarmingly different, it was a surprise that the pair got along at all.
