Doing and Undoing

Doing the things we used to do together
Or even those you used to talk about
Is sad now. That which once was such a tether
Tying us together, now, without
You here, is only painful, since
Your absence is more felt the more I think
Of how you ought to be here. Not to mince
My words: I find I very often sink
Into a little melancholy when
I do a thing we once did jointly, though
I think it's only fair you ought to know
I do recover when I think again
And recognize that when you have come back
I'll do these things again without the lack.
