Can i get a witness
When writing a literary analysis essay, you want to avoid quotes that are only vaguely related to your thesis. Instead, you want to pick quotes that perfectly illustrate your central idea.
For instance, I wouldn't want to use Scout saying, "Pass the damn ham," in an essay about Scout's battle with formal education. That quote, while funny and impactful, is said at her dinner table and has nothing to do with school.
I, however, might do well to use that quote if I am writing an essay about Scout as a rebel, as a tomboy, or as an example of the questionable parenting of Atticus.
