In Joan Didion's novel "Play It As It Lays," the statement reflects a perspective on selfishness and its correlation with physical appearance, particularly in women. The quote suggests that self-absorbed individuals may not face the same consequences, such as gaining weight, as others who are more selfless. It highlights a complex relationship between personal behavior and societal perceptions of beauty and responsibility.

This idea can extend to broader themes within the novel, where characters grapple with identity, morality, and the superficial expectations placed upon them. Didion often critiques the superficiality of Hollywood and its impact on personal relationships, using this observation to underline deeper truths about self-interest and the burdens it carries.
