David Galef : Feud

Once upon a time, when the world was new,
You kicked me, or I bit you.
You were just three and bad at walking;
I was two and barely talking.
When I was five, you sat on me
And tickled me unmercifully.
It’s just too bad your parents heard
And stopped your allowance afterward.
As adolescents, we both swore
That we would wage eternal war.
But now that I’m sixty, I can’t recall
Just what, my dear wife, ever started it all.
