In the book "High Fidelity" by Nick Hornby, the protagonist reflects on the relationships and encounters that shape his life, likening them to a film where he is the main character. This metaphor illustrates how each person he meets plays a significant role, much like supporting actors contribute to the storyline, influencing the protagonist's development and experiences.

This perspective emphasizes the interconnectedness of human relationships, suggesting that everyone has an impact, whether small or large, on our personal narratives. It invites readers to consider how their interactions shape their lives and the roles others play in their journey.
