Billy shrugged his shoulders, then shook his head, smiling a little. "Naah, I've been doing it since I got here. I took a little karate when I was younger, and when I got here my freshman year, the gym wasn't all that packed, so I would spend time in there." Billy wasn't a social butterfly back then. He'd really opened up since he came to the school. "But sometimes I just need a break from schoolwork, or the journals. You can't eat all the time." He chuckled and took a sip of his soda.
