THE GOOD: Always someone around to talk to, eat with, hang, study, and cheer on your favorite team. Convenience, Great Food, Beautiful House. Lots of House Boys to counsel you like a big brother (and built-in dates for formals).
THE BAD: Can get noisy, even during "quiet hours". You sometimes have to wait on a shower. Room mates who snore (gets you ready for marriage)
THE UGLY: Election time when you are close friends with both who are running for president
, the smell of stale beer in the stairwell on Sunday mornings, someone pounding (ok, playing) the piano when you are trying to sleep -- my room was directly over the piano.
