"Yeah, he doesn't have another one. I'm not sure whether I wish we were in an earlier class or not. I mean, it didn't look like the room had been previously partially demolished, but that doesn't mean much."
"It's so bad," he says. "I bet he doesn't even know, and if he does he obviously doesn't care - there's people who have real things to be scared of, things where it doesn't matter if you only see them for a second, it'll still fuck up your whole day.
