In this passage, the character walks by someone without acknowledging him, symbolizing her detachment from both human connection and her own physicality. Her indifference highlights a sort of superiority over conventional desires and vulnerabilities associated with femininity. It suggests that she views herself as transcending the weaknesses that come with being human, distancing herself from societal expectations.
Moreover, this reflects a broader theme in "One Flew Over the Cuckoo's Nest" where characters grapple with authority and the constraints of society. The choice to ignore not just the man but also her physical attributes implies a rejection of traditional gender roles and a desire to assert herself beyond the superficial traits that define many women. It captures a complex interplay of power, identity, and the struggle against conformity.
