I think that the bid that Miss Walters placed on the pie at the Benefit is an example of revenge that is justified. By placing the bid, she reminded her daughter of the "Terrible Awful," but did so in a way that would not be apparent to anyone who did not know the story. Miss Walters was angry with her daughter for placing her in a retirement home, and this was a clever way to remind her that Miss Walters knew her darkest secret. One example of revenge that went too far was Skeeter's prank with the toilets on Hilly's lawn. Though this was a humorous scene, Skeeter should have known that it would have major consequences.
