Enter the roommate.

For many of us, college was our first experiencing sharing close quarters with someone our exact age. Sure, I had bunked with my younger brother, but I was clearly in charge. In a dorm situation, it's more of a cautious dance. Who gets to choose the music? Who has to use headphones? And what about overnight guests? Lest The Man from UNCle get too comfortable in his socially-backward ways, I threw in a foil right away to help him "man up."
