Sharon Esther Spitz is the main character of the series who has unrealistic luck. Sharon always gets into trouble and messes up unlike every other teen, but she always learns from her mistakes, sets things right in the end, no matter what the situation and will only be given affection when with those who have status or money, etc, or if she has status, or money, etc., for instance, pretending to be talking money, etc.. Sharon is also known to be a clumsy girl and would usually end up embarrassing herself somehow. Sharon's rival is Nina Harper who attends Sharon's junior high school and later senior high school. Sharon's family members include her father Richard (a musician), her mother Helen (a therapist), her older brother Adam, and her younger brother Josh.
Sharon's character is based on the early life of the actress Alicia Silverstone.[citation needed] Just like Silverstone, Sharon is an animal rights supporter and a vegetarian. Many times, her braces form a central part of the show's plots, as they are magnets, which leads Sharon to unintentionally attract different objects and get into embarrassing situations, although they do help her occasionally. In the first episode, they are shown to pick up radio and telephone frequencies, though it is never explained how.
