So here's this guy in my year whom i have never seen eating for the entire year since i came to this school. He's very skinny, though not to the point of being outright skeletal. He's also quite pale, but since he's white that may be just his skin color. He doesn't hang around with others very much, and his friends are mostly nerds who achieve really high grades. He doesn't appear to have emotional problems though. Also, he seems quite stable, not losing weight continuously.
