1. Try to get to know each other.
2. Don't expect too much...room/suitemates don't have to be best friends. Getting along with each other is all that is necessary.
3. Be open, ask, listen, discuss. Don't wait until things get out of hand. If you are not open with your room/suitemates, your frustration may keep building until you blow up and say things you really don't mean. This could result in hurt feelings. Before it gets to that, talk it out. Tell your room/suitemates in a mature fashion what is irritating you and help them to understand why.
4. Be sensitive to each other's moods, everybody has bad days, so try to understand when your room/suitemates has one too.
5. Share what you can and clearly state what you are not comfortable sharing.
6. When things can't be worked out between suitemates, seek assistance from someone else, such as your RA or RD.
7. Room/suitemates can be fun and they sure can help ease the loneliness you may feel sometimes. Share successes, say thank you, show common courtesy, and let the other person know when things are going right, as well as when things are going wrong.
