What does Miss Maudie tell Scout about Boo?

In chapter 5, Scout has an enlightening conversation about Boo Radley with Miss Maudie while sitting on her porch. After Scout asks whether Boo Radley is still alive, Miss Maudie tells her that Boo is still living and that he simply chooses to stay inside. Miss Maudie then explains to Scout that Boo's father was a religious fanatic and interpreted the Bible literally. Maudie elaborates on Mr. Radley's extreme views and believes his callous nature more than likely affected Boo's reclusive behavior. Maudie then tells Scout that most of the neighborhood stories she hears about Boo are false rumors. Miss Maudie then informs Scout that Boo Radley was a kind, respectful child. Maudie says, "He [Boo] always spoke nicely to me, no matter what folks said he did. Spoke as nicely as he knew how" (Lee 46). When Scout asks Maudie if she thinks Boo is crazy, Maudie responds by saying that if he was not, he should be now. Maudie also tells Scout that she is unsure about the secrets and mysteries that are hidden behind the Radley's closed door.
