In Harper Lee's classic novel "To Kill a Mockingbird," Aunt Alexandra comes to Maycomb to help her brother Atticus with the raising of his children, and she joins the town's local society by joining the ladies' social circle and establishing a missionary circle of her own. This allows her to interact with the other ladies in Maycomb.
Interestingly, no controversy arises at all from the fact that Aunt Alexandra has left her husband down at Finch's Landing. In addition to the missionary circle, she also has lengthy visits with Miss Stephanie and drinks coffee with Miss Rachel. She also signs up to be the secretary of the Maycomb Amanuensis Club.
In a way, Aunt Alexandra is the most mainstream person in the entire Finch family. While Atticus understands the way that the town works, he does not involve himself in local society. He has earned the town's respect because of his intelligence as an attorney and his integrity, but he is definitely not "of" the town. Aunt Alexandra is much more concerned with finding acceptance in the town, even gaining some renown in the community for her fine refreshments. Scout, Atticus' daughter, has inclinations that are much closer to her father's in terms of the amount of socializing she wants to do, and the battle that she and her aunt have over the need to be "ladylike" is one of the novel's conflicts.
