DUBUQUE, IA—Bashful Clark College sophomore Mandy Schumacher, 20, has spent the last month unsuccessfully trying to forge a personality from scratch, friends of Schumacher said Monday. "She's been introverted for so long that she just doesn't have a clue how to present herself to the world," Schumacher's roommate Krista Vezmer said. "One day she's, like, expounding on the modern ramifications of the Civil War, and the next, she's dancing on tables at Noonan's during Happy Hour." Vezmer added that she thinks Schumacher should stick with mousy.
