Maddy is Laura's cousin. She appears only in the diary's very early entries and is referred to only once or twice later on. Aside from being a friend and confidante, as well as a relative, Maddy plays an important role in Laura's life because of the clothes she lends Laura - tight, sexy, and fun. Laura's discovery of the sensual pleasure at wearing these clothes marks the beginning of her emerging, precocious, dark-sided sexuality.
