A letter never sent is like...?

Answer 1

a song never sung a flower never bloomed a gift never opened a book never opened a prize never claimed a feast never savored roses left to wilt on the vine a bud that never sprouts a butterfly that never emerges a candle never lit a treasure locked in a safe a fine wine never uncorked sweet cologne with the seal unbroken a song left unsung a treasure that goes undiscovered a symphony never performed
