From To Kill a Mockingbird:
Mr. Radley walked to town at eleven-thirty every morning and came back promptly at twelve, sometimes carrying a brown paper bag that the neighborhood assumed contained the family groceries. I never knew how old Mr. Radley made his living— Jem said he “bought cotton,” a polite term for doing nothing
Was it ever revealed (elsewhere in the book or in the movie, or by Lee herself) what Mr Radley did for a living and what he was carrying in the paper bag?
