Discuss your likes and dislikes openly. Share housekeeping responsibilities. Set up fair ground rules, and agree to abide by them. Patience, courtesy, consideration, a willingness to compromise, and of course good communication are essential. If you cannot get along or resolve your differences with your roommate, discuss your problem with the resident assistant or housing director.
Staff is there to help.
New people are everywhere. In addition to your roommate, you can meet people in the dining hall, the laundry room, recreation centers and classes. All you have to do is make a small effort to be available. In fact, it's far easier to meet people during those first few days when everyone is new. If you wait until relationships have formed, you may find it more difficult to make friends.
