Why is Scout anxious to start school?
The narrator of the novel, To Kill a Mockingbird, Scout was obviously a highly intelligent child, modeled after author Harper Lee herself. Scout could already read and write (including cursive!) before entering the first grade, and her blossoming writing career (though unmentioned in the story) was probably already being nurtured by her nightly readings with Atticus. Maycomb was also a boring little town with little to do or see, so for Scout, school was expected to be a great new adventure. She and Jem seemed to have few playmates or close friends besides Dill, so school was undoubtedly something Scout was looking forward to absorbing.
Scout was also depicted as a precocious child who loved nothing better than to compete with her brother. Since Jem went to school, Scout wanted to as well. School was also an outlet for Scout to become her own person rather than the "younger" of the two Finch children. During her first experiences as a child in school, Scout developed her own friendships as well as her own enemies and was not afraid to show both her allegiance to a friend (despite his background) as well as her displeasure to anyone who criticized her or her family. School provided an opportunity to develop the character of Scout as well.
