For those of you who live with other people, what is acceptable as far as letting other people stay overnight? I currently share a house with 6 other people. We actually have a house rule that states that you can't have people overnight more than two times a week but with one guy, we never really enforced it because he and his girlfriend were generally very quiet and we only noticed her if she happened to go into the kitchen when someone else was there.
Another guy, however, has been bringing his girlfriend over frequently, more than the allowable two times a week, and while they're not screaming and stuff, I can definitely hear them talking in his room, which gets annoying when I am trying to sleep. I am also concerned that the girlfriend seems to have a key to the house because I saw her just walk into the house without ringing the door bell or the guy letting her in.
