Roommate Traits: You only see her about once a week -- maybe. And she's just there to get five more pairs of underwear and steal away, back to her boyfriend's dorm or her parents' house or wherever it is that she dematerializes to.
Helpful Tips: If you had dreams of having a roomie/bff, you're going to have to let those dreams die. Having an absentee roomie is actually a great motivator to push yourself to make friends outside your room and, when you're home, enjoy some time to yourself. Think of it as practice for adult life -- when you live alone someday. Also, for God's sake! Throw some parties in your room!
