Anonymous - Last Sun: An Homage to Philip Larkin's The Trees lyrics

The boy is near adulthood Like a book when it is done; The last page is the last sun, What was unknown is understood Is it that everything's changed Except him? No, he changed too. The effect life has on you Is not seen until you've aged. Yet still the boy, old and young Won't let go of yesterday. The kid at heart swept away, A life just begun, begun, begun.
