In "The Amber Spyglass" by Philip Pullman, there is a poignant moment where the characters express their deep bond and understanding of love. One character suggests that if they find new partners and marry, it's essential to treat those partners well. The idea is to avoid comparisons with their past relationship, which was significant to them.

They agree that maintaining a connection is vital, promising to reunite once a year for a brief time. This sentiment reflects the complexity of love and the ways people navigate the emotions tied to past relationships while cherishing those memories even as they move forward in life.
