In the book To Kill a Mockingbird why do children spit on gate?

In Harper Lee's "To Kill a Mockingbird," the act of spitting on a gate is not actually depicted. There's no mention of children spitting on gates in the book.

It's possible you're thinking of a different book or movie, or perhaps a scene that has been misinterpreted or adapted from the original story.

Could you please provide more context or details about the specific scene you're referring to? This would help me identify the source of the confusion.
