This excerpt from Nick Hornby's "High Fidelity" emphasizes the significance of shared interests and values in relationships. It suggests that the differences in personal tastes, such as music and films, can indicate deeper incompatibilities. When two people have fundamentally opposing preferences, it can create discord that may jeopardize the future of their relationship.

The quote also implies that acknowledging these differences is crucial. Pretending that they don't matter can lead to unrealistic expectations about the relationship's viability. Ultimately, Hornby highlights the importance of compatibility in personal passions as a key component for a healthy and lasting partnership.
