In Larry McMurtry's "Lonesome Dove," the complexity of gender roles is examined, particularly through the lens of vanity. The quote reveals a struggle against societal expectations, highlighting a double standard where tolerance for vanity is expressed differently between men and women. It suggests that while female vanity may be accepted, male vanity is criticized, pointing to the harsher judgments placed on men in terms of their self-image and behavior.

This distinction raises questions about vulnerability and the performance of masculinity in the context of the story. It reflects the characters' struggles with identity and societal norms, illustrating how these expectations can shape their interactions and relationships. Ultimately, McMurtry invites readers to reflect on the implications of these biases and the complex dynamics of human nature.
