Do you guys think all of this time spent with my 'best friend' will drive me nuts?
omg... I was always and still am afraid of that though. I can see the fights now...
Well, then, your best bet is to get a new roommate/room, then, if you fear the fights.
I would suggest what most college housing authorities/managers suggest: Do NOT room with someone you know. It could easily fuck up a friendship, even the tightest knit one. It's best to start anew.
