Marriage is not
a house or even a tent

it is before that, and colder:

the edge of the forest, the edge
of the desert 
                    the unpainted stairs 
at the back where we squat 
outside, eating popcorn

the edge of the receding glacier

where painfully and with wonder
at having survived even
this far

we are learning to make fire 

Masons, when they start upon a building,
Are careful to test out the scaffolding;

Make sure that planks won’t slip at busy points,
Secure all ladders, tighten bolted joints.

And yet all this comes down when the job’s done
Showing off walls of sure and solid stone.

So if, my dear, there sometimes seem to be
Old bridges breaking between you and me

Never fear. We may let the scaffolds fall
Confident that we have built our wall.
