I'm not brave, loyal, or ambitious, but I do think differently than others, and have been called smart before, even though I don't think so. I think I'm insane.
My own house. Boarding schools suck, in my opinion.
Also Ravenclaw. I place high value on intelligence. Ambition, not so much, but Slytherin would probably be my second choice. Loyalty is something to be earned, not given. And bravery? **** that. I have just enough bravery to not be a coward, but not so much as to be an idiot.
