The Day Flies off Without Me

The planes bound for all points everywhere
etch lines on my office window. From the top floor
London recedes in all directions, and beyond:
the world with its teeming hearts.

I am still, you move, I am a point of reference on a map;
I am at zero meridian as you consume the longitudes.
The pact we made to read our farewells exactly
at two in the afternoon with you in the air
holds me like a heavy winter coat.

Your unopened letter is in my pocket, beating.
