In "A Regular Couple," Curtis Sittenfeld explores the theme of insecurity through a moment that reveals a deep-seated vulnerability. The narrator expresses an overwhelming desire to protect their cribbage game, which symbolizes a more significant aspect of their life, suggesting a fear of judgment or exposure. This instinct to cover the board with their hands signifies an emotional reflex tied to self-preservation and a struggle to maintain privacy in personal matters.

This poignant quote highlights how insecurities can surface in everyday situations, reflecting the broader human experience of wanting to shield oneself from scrutiny. The act of shielding the game not only represents a physical action but also illustrates the psychological barriers people erect in relationships. Overall, Sittenfeld captures the complexity of human emotions and the instinctive reactions that arise when faced with vulnerability.
