I listen close

I unlocked your side.
It got dark and we went north.
Trying to peek through driving snow
And I listened to you low.
Outside the wind got fast and cold.
And made a tiny sound, the ghostly Blow.
You sang low, I listened close.
I tried to join you in your note.
The 3 parts surprised us both:
We 3 you and me and the Blow!
(it will be grey when we get home,
I listen close, you keep me warm.)
