Sara Louise thinks that one advantage of being crazy is that she will no longer have to struggle against the knowledge that she might not be normal. She ruminates,
"I was quite sure I was crazy, and it was amazing that as soon as I admitted it, I became quite calm. There was nothing I could do about it. I seemed relatively harmless...I could probably live out my life on the island in my own quiet, crazy way, much as Auntie Braxton always had. No one paid much attention to her...Caroline was sure to leave the island, so the house would be mine after my grandmother and my parents died...I could crab like a man if I chose..."
Sara Louise thinks that, if she really were crazy, then people would accept her as such, and would not expect her to act in accordance with socially accepted norms. They would no longer observe her behavior with constant scrutiny, and the thought of not having to continually keep up the appearance of outward conformity to approved social standards fills Sara Louise with a sense of relief. She reflects,
"Crazy people who are judged to be harmless are allowed an enormous amount of freedom ordinary people are denied. Thus as long as I left everyone alone, I could do as I pleased. Thinking about myself as a crazy, independent old woman made me feel almost happy".
Sara Louise's thoughts about being crazy stem from her frustration and repressed bitterness towards her sister Caroline. Although they arguably have a lot of truth to them, they are obviously not a good solution to her problems, but for the moment, Sara Louise is at her wits' end, and her ideas make a lot of sense to her (Chapter 13).
