I want to remember everything

I don't want to lose a single thread
from the intricate brocade of this happiness.
I want to remember everything.
Which is why I'm lying awake, sleepy
but not sleepy enough to give it up.
Just now, a moment from years ago:
the early morning light, the deft, sweet
gesture of your hand
     reaching for me.

[Mary Oliver {1935- }, 'I Don't Want to Lose', from Felicity: Poems]
