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 pain

For unremembered lads that not again Will turn to me at midnight with a cry.

Thus in 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 me A little while, that in me sings no more.	

-- Edna St. Vincent Millay

i have been looking for this poem since high school and now i found it

in my brit lit class i remember reading the first and last 2 lines 

in our text book. and they summed up the summer before my senior year so

perfectly, that i have been looking for this poem ever since
