I found this incredibly beautiful

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 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.
