What does Scout admire about Miss Maudie?

Scout admires Miss Maudie's way of treating everyone the same, no matter if they are children or adults, or white or black members of the community. Scout is a sensitive child who notices when she is not being treated fairly, and resents such treatment; Miss Maudie is very fair, and she shows respect to Scout and Jem as much as she does to their father Atticus.
Scout also has to endure various female influences in her life telling her how to act a like a lady. Miss Maudie shows Scout that being a woman does not mean she has to be weak or quiet, or someone other than herself. This is a valuable lesson for Scout, who resists unhelpful advice from other women in her life—like Aunt Alexandra, who has a rather old-fashioned perception of being a lady, which Scout does not appreciate.
