Scaffolding by Seamus Heaney
Masons, when they start upon a building,
Are careful to test out the scaffolding;
Make sure that their planks won't slip at busy points,
Secure all ladders, tighten all 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 seems to be
Old bridges breaking between you and me
Never fear. We may let the scaffolds fall
Confident that we have built our wall.
