just kidding. You'll definitely become friends with your roommate and floor mates, just naturally. You can also join clubs and organizations to make friends. If you are in any small classes, you can make friends. You can also make friends by talking to strangers in the dining center, library, going out at night, etc. The best part about making friends in college is that EVERYBODY is looking for them, so there is definitely no shortage of potential buddies. Good luck!
Join clubs. Mostly likely the people in your club will enjoy some of the things you like. Have a study date with someone in your class(s). Get a part-time job. You will earn money and meet new people. If you live in a dorm, make an effort to introduce yourself to people who live on same floor as you.
