“The Sound of Forgetting” by W.S. Merwin

All night while the rain fell
the dark valley heard in silence
the silent valley did not remember
you were asleep beside me
while the rain fell all around us
I listened to you breathing
I wanted to remember
the sound of your breath
but we lay there forgetting
asleep and awake
forgetting a breath at a time
while the rain went on falling around us
