In Tad Williams' "To Green Angel Tower, Part 1," a conversation unfolds among characters regarding the emotional weight of songs. Aditu expresses that the songs they cherish most are those that reflect loss and longing. This sentiment suggests that music holds a deeper meaning when it connects to experiences of absence and nostalgia.

Josua adds to the discussion by emphasizing a profound truth: the value of something often becomes apparent only once it is lost. This exchange highlights the universal human experience of appreciating what we have and understanding its significance only after it is gone, making loss a powerful theme in both their music and lives.
