"What lips my lips have kissed, and where, and why,I have forgotten, and what arms have lainUnder my head till morning, but the rainIs full of ghosts tonight, that tap and sighUpon the glass and listen for reply,And in my heart there stirs a quiet painFor unremembered lads that not againWill turn to me at midnight with a cry.Thus in the winter stands the lonely tree,Nor knows what birds have vanished one by one,Yet knows its boughs more silent than before:I cannot say what loves have come and gone,I only know that summer sang in meA little while, that in me sings no more."
Edna St. Vincent Millay
