It suggests that there are countless stories, places, and perspectives yet to be discovered, inviting readers to expand their horizons and embrace the unknown. This idea resonates throughout the book as Oskar uncovers hidden connections and truths, reminding us that life is filled with surprises waiting to be explored.
