Howdy Neighbor

Nothing unhappens, and yet
Only the past’s ever changed,
Only the past is going

To change, and the past’s always
Changing when you check on it.
You can’t unhappen a thing,

And yet everything and you
Will have happened to have been
Erased for other has beens.

Someone opens their garage
And comes galumphing over
The courtyard to talk to you.

Neither of you will recall
This moment terribly long,
Never not part of what’s been.
