Tell you what, I'll make you a deal: I won't ever wonder aloud why you're in Gryffindor when you're so scared you hate spiders so much, so long as you don't ever wonder aloud how come I'm in Gryffindor when I never want to take a broom more than four feet off the ground.

I'll even kill any spider you find in the room for you, if you ever find one. They don't bother me all that much, really.
