What I found interesting is the way that the narrator’s husband coddles her and treats her more like an infant than anything. The bedroom he even has her take is a nursery. She is hardly allowed to do anything besides eat, breathe and sleep. She makes an effort to point this out as often as possible but she doesn’t do it with a tone of malice until the end where she begins to completely go insane. Pretty much every other line the narrator is talking about something that her husband, John, won’t let her do.
To be honest I don’t quite understand the ending. Is the narrator really free and liberated? Is her mind free or has her “condition” been freed from inside herself for her husband to observe? But why did her husband faint?
