On an Echoing Road

On an echoing road, trotting in unison
Now out of step, now as one again
Are two horses saddled together
Guided by a single hand
The needle and the pen, the habit of work
And the sly urge to quit the habit, make friends with each other
Then separate, then reconcile again....
O my slow steeds, pull now together;
From here I can see the end of the road
