The quote from Annie Proulx's "Brokeback Mountain" reflects the profound tension and danger that can arise from hidden truths and suppressed emotions. It suggests that ignorance can sometimes be a protective shield, while knowledge can lead to perilous consequences. The fear of what might be uncovered emphasizes the intense emotional struggles faced by the characters, particularly in a society that harshly judges their love.

This line encapsulates the essence of the story, illustrating how the characters grapple with their identities and the societal constraints that threaten their relationship. The weight of unspoken truths creates an atmosphere of anxiety and foreboding, highlighting the risks involved in confronting one's desires and the potential fallout from decisions made in secrecy.
