Laurie has created Charles to serve as his bad-little-boy alter ego in Shirley Jackson's short story, "Charles." Laurie has apparently been pampered somewhat by his mother, and she worries before he heads off to kindergarten that he may pick up some bad habits. Sure enough, they begin appearing at home at an alarming rate. We can assume that Laurie conjures up the imaginary Charles in order to explain his own bad behavior without having to admit to his parents that the misbehavior comes from him. Laurie thus remains the innocent child that his parents see in him while still admitting to his wrong-doings at school. Critics have explored the possibility that Laurie is suffering from the early stages of a split personality, and his creation of Charles lends evidence to this. Surely, his laughing "insanely" at home is a hint by the author at the problems surrounding Laurie.
