Again and again and again

H and I heard this song on the way back to Virginia from Connecticut last weekend and it's been in my head every since.

******

What lips my lips have kissed, and where, and why
I have forgotten, and what arms have lain
Under my head till morning; but the rain
Is full of ghosts tonight, that tap and sigh
Upon 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 the winter stands the lonely tree,
Nor knows what birds have vanished one by one,
Yet knows its boughs more silent then 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
