Difficulty: Moderately Challenging
Step1
If your roommate spends a lot of time in your room alone, try including him/her in some of your activities. Most of the time, people will stay in their room if they don't know anyone or haven't made many friends. Give them a chance.
Step2
If your roommate has annoying habits, there are steps for that too. The first and probably best step is to talk with them about the problem. Explain your side of the issue and why it bothers you. Most of the time, they will understand where you're coming from.
Step3
If you really can't stand your roommate anymore, ask your RA if there is something you can do about it. Perhaps he could do a switch or get something worked out with your residence hall director. Just keep trying!
