In the book "High Fidelity" by Nick Hornby, a significant theme revolves around relationships and the fear of loss. The quote suggests that being overly cautious or paranoid about losing someone can lead you to choose a partner who lacks appeal to others. This choice may seem safe, but it also limits the potential for a meaningful connection. The idea emphasizes the importance of embracing vulnerability in relationships.

Hornby highlights the tension between the desire for security and the willingness to take risks in love. If one only seeks out people who are "unlosable" due to their lack of desirability, they miss out on deeper relationships that come with the possibility of loss. Ultimately, the quote invites readers to reflect on the dynamics of love and the necessity of accepting uncertainty in order to cultivate rewarding companionships.
