How I'd resolve a conflict between me and a roommate who is always very loud at night? So, I think I would probably try to speak with him about my dissatisfaction. Maybe he thought that he did not irritate me. Probably it would be successful. If it would not help, then I could write a complaint about this situation. I think that the complaint would definitely improve this situation. At the worst I could try to find a new room or a new roommate) It would depend on conditions of using this room.
