In Jodi Picoult's book "Second Glance," the concept of belonging to others is highlighted through the idea that sacrifices create lasting connections between individuals. Making a sacrifice for someone implies a deep bond, as it intertwines their lives in meaningful ways. When you give up something for another person, it signifies a commitment that goes beyond mere friendship, forging a unique relationship based on care and mutual respect.

This powerful notion suggests that our actions towards others have profound implications on our relationships. By willingly giving a part of ourselves—our time, energy, or even preferences—we share a piece of our essence with them. Consequently, this creates a sense of ownership of one another's souls, reinforcing the belief that we are not just solitary beings but are intrinsically linked through our acts of love and sacrifice.
