How do Aunt Alexandra, Miss Maudie, and Scout follow Atticus' example by returning to the missionary circle? Why is this so significant for Scout?

Miss Maudie thinks that the town has paid Atticus a high tribute by trusting him to do right and uphold justice. These people are the small handful who know that blacks should be given justice, and who have "background." The two women are quite shaken, but then join the other women effortlessly. Scout feels proud of her Aunt and of Miss Maudie, and for the first time feels inclined to be ladylike, thinking that, "if Aunty could be a lady at a time like this, so could I."
