One of the most incredible transformations in maturity is Scout's perception of Arthur "Boo" Radley. In the beginning, she sees Boo as an object of fascination—a myth more than a man. She, Jem, and Dill spend countless hours inventing games about him and trying to entice him to emerge from his home. Scout both fears and is fascinated by the idea of Boo.
Gradually, though, Scout begins to shift the way she sees Boo. In the final scene, Boo asks her to take him home in a soft whisper. Scout wants to defend Boo's integrity and says that she would never allow Boo to "lead [her] home." Instead, she asks him to bend his elbow a little so that she can slip her hand inside. This is an intentional move with foresight against the rumors generated by Miss Stephanie Crawford:
If Miss Stephanie Crawford was watching from her upstairs window, she would see Arthur Radley escorting me down the sidewalk, as any gentleman would do.
This shows a great growth in maturity compared to Scout's games involving scissors and notes.
Scout also matures into a more genuine appreciation of her father. Early in the novel, she laments that Atticus doesn't do anything worthy of admiration:
Atticus did not drive a dump-truck for the county, he was not the sheriff, he did not farm, work in a garage, or do anything that could possibly arouse the admiration of anyone.
These views reflect a childlike view of the work Atticus does, but Scout comes to understand—at least to a greater extent—that her father works to defend values and principles for everyone, regardless of background. She is shown a visible representation of his value in the community immediately after the trial, when the black people sitting with her in the balcony all rise as Atticus walks by—and Reverend Sykes asks that she do the same to show her respect.
Thanks to Atticus, she also matures in her understanding of class differences. Although the Ewells and Cunninghams both have less money than the Finches, her views in how they differ are transformed through various conflicts. Early in the novel, she attempts to beat up Walter Cunningham because she feels he has gotten her into trouble due to his lack of lunch money. She boldly informs their teacher of the various trials of the Cunninghams due to their poverty. Later in the book, however, Aunt Alexandra calls Walter Cunningham "trash," and Scout is livid. Jem jerks her away, and Scout replies,
It was her callin' Walter Cunningham trash that got me goin’, Jem, not what she said about being a problem to Atticus. We got that all straight one time, I asked him if I was a problem and he said not much of one, at most one that he could always figure out, and not to worry my head a second about botherin' him. Naw, it was Walter—that boy’s not trash, Jem. He ain’t like the Ewells.
Scout has come to understand that wealth—or the lack thereof—doesn't determine a person's worth. She no longer feels that Walter Cunningham is a lesser person because he has less money, and that is a direct influence of watching her father interact with the Cunninghams to demonstrate respect for their hard work and values.
