Miss Maudie is part of the world where "fragrant ladies rocked slowly, fanned gently, and drank cool water" (24.53), but this rose never lets others forget her thorns. Unlike Miss Stephanie and Mrs. Dubose, however, Miss Maudie uses her sharp tongue to counter meanness rather than to perpetrate it.
