Girder by Nan Cohen

The simplest of bridges, a promise
that you will go forward,

that you can come back.
So you cross over.

It says you can come back.
So you go forward.

But even if you come back
then you must go forward.

I am always either going back
or coming forward. There is always

something I have to carry,
something I leave behind.

I am a figure in a logic problem,
standing on one shore

with the things I cannot leave,
looking across at what I cannot have.
