is scout's first day like she expected?

Scout eagerly awaits her first day of school. She is excited about the prospect of finally starting school, but her first day of first grade leaves her extremely disappointed.

Scout is a very intelligent and precocious child who learned how to read through her natural instinct, sitting on Atticus's lap and following along in his book. She doesn't understand that she loves to read until her teacher tells her she can't read anymore: this shows that reading was a pleasure and a freedom she had taken for granted all her life until it is denied to her. The value of some freedoms can't be fully understood until a person is forced to part from them.
