On the cusp of the transition from childhood in to adolescence, 14-year-old Mick is tall for her age and very thin, with short blond hair and blue eyes. She often leaves Bubber/George in charge of watching their baby brother Ralph so she can sneak off to smoke a cigarette. Although Mick is absorbed in her "inner room" thinking about music, she heroically swings into action to help her family—defending her little brother Bubber's desire for a pink costume, or offering to quit school to work at Woolworth's to support the family. Mick is fascinated by her family's new boarder John Singer and starts following him around. She also begins an awkward sexual relationship with her older next-door neighbor Harry Minowitz. Mick's character is somewhat autobiographic, and reflects Carson McCuller's personal views on coming of age.
