In To Kill A Mockingbird, Aunt Alexander is Atticus's sister and she comes to help out with the children because Atticus will be very busy with Tom Robinson's trial. She has very different opinions from Atticus in how to raise the children and does cause some difficulties, especially with Scout as she tries to impose her "feminine influence" on the tomboyish Scout. At the beginning, her character traits reveal her stubbornness and her awareness of social classes; also her tendency to be domineering, even bullying Atticus into talking to Scout about her heritage, making her cry, because she is confused at her father's changed approach .
Despite the children's unhappiness, Aunt Alexander does do her best for her family and, having had a "feeling" about the potential for something to happen now feels partly responsible and guilty, for not having protected the children better, as she says:
"Atticus, I had a feeling about this tonight—I—this is my fault..."
Aunt Alexander is worried about Bob Ewell's reaction, even though Tom has been found guilty. She cannot understand why he still holds a "running" grudge against everyone:
"I know how that kind are about paying off grudges..."
Aunt Alexander does become more accepting and recognizes the double standards in Maycomb; thus, revealing her sincerity, loyalty and devotion and also her feelings of guilt, in expressing herself in chapter 29.
