In “To Kill a Mockingbird” what causes the “shiny clean line” on the otherwise “dull wire” of scout’s costume?

In "To Kill a Mockingbird," the "shiny clean line" on Scout's costume is a symbol of protection and innocence. Scout wears a ham costume to the Halloween pageant, and on the way home, she and Jem are attacked by Bob Ewell. During the attack, Scout's costume is ripped, but the wire that holds it together creates a "shiny clean line" on her otherwise "dull wire" costume. This line represents a barrier between Scout and the violence that surrounds her. The wire also symbolizes protection, as it shields Scout from harm during the attack.

Furthermore, the "shiny clean line" also represents innocence, which is a central theme in the novel. Despite the violence and racism in the town, Scout remains innocent and pure. The wire represents her innocence, and the "shiny clean line" symbolizes the purity that remains within her. It is also important to note that the wire, which is a common household item, represents the simplicity and innocence of childhood. As Scout grows older and experiences more of the world's darkness, her innocence will be tarnished, but for now, the wire and the "shiny clean line" serve as symbols of her youth and purity.

Overall, the "shiny clean line" on Scout's costume represents the themes of protection, innocence, and purity. It serves as a reminder that appearances can be deceiving and that people should not be judged based solely on their outward appearance.
