What they all said, but here's another one.
My first year was at Northeastern, in 1982-1983. First place I was located was known as "Roach Villa" by its residents, across from the Museum of Fine Arts. It was a small apartment, and I was placed with three other guys who were, like me, away from home for the first time. The building had a lot of "character".

Besides the roaches, it had an old-style open elevator, which even worked at times.
The first week, before classes started, was party time, especially for two of my roommates. They partied to all hours, insisting that I and the remaining roommate party with them. This sucked ass. Sleep was difficult to get before 04:00.
After classes started, they didn't calm down and the RA was no help (tried to prevent us from leaving), so I and the only other
sane roommate went to to Housing and got ourselves relocated. We were given a room of our own in one of the larger dorms. This worked out pretty well, and led to some interesting learning experiences. For instance, the dorm was coed by floor, but the first time a girl went into our floor's bathroom was a bit of a surprise. I got over it pretty quick, though.

It was all stalls, after all.
Later, one of the other two roommates appeared to clean up his act. The remaining one disappeared, apparently not making the adjustment successfully.

but not my problem. Note: no one here was a true asshole (well, maybe the RA), it was more a matter of there are some people you can be buddies with but you just can't
live with 'em.
