In Margaret Atwood's novel "Alias Grace," the narrator expresses a deep discomfort with being observed while eating, highlighting a fear of vulnerability. The idea that showing hunger could lead to exploitation emphasizes a theme of power dynamics in human relationships. The character's desire to conceal their needs reflects an understanding that revealing one's desires can make them susceptible to manipulation.

This perspective suggests that a defense mechanism may be to suppress wants altogether. The narrator believes that withholding emotions and desires is a strategy for safeguarding oneself against potential emotional or social repercussions. Such insights reveal the complexities of human interactions, where showing vulnerability can lead to disadvantage.
