Her experiences in the asylums are memorable and interesting. It is hard for the reader to forget her acquaintance, Joan, who is almost like a friend to her despite the fact that she had dated the same man: Buddy Willard, a medical student.
The ambiguity of the relationship between Joan and Esther is a recurrent theme. Esther states that she does not like Joan. Yet she also admits that she will always treasure her. "I thought I would always treasure Joan. It was as if we had been forced together by some overwhelming circumstances, like war or plague, and shared a world of our own."
Interestingly, Joan's final decision foreshadows Sylvia Plath's destiny, and one cannot help but wonder about the blurred boundaries between fiction and reality.
