My first college roommate's name was Charlene. We were "friends" in the sense that we occasionally talked, if she were in a good mood. There were sometimes long stretches of no communication or interaction with one another if she was in one of her bad moods. Maybe a better way to describe our relationship is that we occasionally got along and otherwise stayed aloof. Is there a term for that? We only stayed roommates for my freshman year so it wasn't too big a deal.
