Your roommate may be the person who wakes you up when you sleep through your alarm, who takes messages for you, and who brings you soup when you are sick. She may get you invited to great parties and get you involved in clubs or sports. Your roommate might lend you her favorite clothes, swap jewelry with you, and keep you up laughing for half the night. Or your roommate might simply be the person you share a room with for a few months. In any case, this person will be an important figure in your life.
