The narrator of To Kill a Mockingbird is a young girl, Scout, though the story is told in retrospect. The novel is a coming-of-age story where Scout begins to understand the injustices in the world. In this tone example, Scout acknowledges the things that she took from neighbor Boo Radley without having given anything back. Though she is talking about literal things here, her nostalgia about not having done enough for Boo extends to intangible things as well.
