I found
this on my way to the Great Hall yesterday.
I haven't talked to Hiei before, even though we're in the same year. Maybe it's because he's in Slytherin. I'm not prejudiced against Slytherins, but most of the ones I've tried talking to aren't very friendly towards people in the other houses, so I kind of started avoiding them after a while. >_>
Then again, from what's written here, he doesn't seem like a bad person, just kind of sad. I should try to cheer him up some time!
