Alright, I'll play. = )

Why I'm happy: Well, room-mate is a good chance to get to know her better as a person. You never really see all the sides of someone until you've lived with them for a few months.
That, and... well, I'm sick of being around people I can't depend on. I've been in a few situations that were sticky in my life and had to solve them while others panicked or cowered. Seeing that has some negative effects on how you view those people when they're people that you see every day, and it can cause problems and stress. It's even more stressful with that lurking feeling that one day you might have to solve things alone again just can't seem to get out of the back of your mind, and I never found a solution for that. It'd be nice to finally have someone I can depend on and trust, and hold some respect for.
That's someone I'd be... comfortable with.
On a slightly less serious note, she'd probably help me get rid of the body of the annoying guy across the hall. *shifty eyes*
