A Stray Thought

I had a thought this morning –
It was a good one, too –
But I had other duties planned,
Other things to do.

And so I set the thought aside
For later (or so I thought).
Unfortunately, between now and then
My thought I quite forgot.

Now, later turns to never –
Or at least to “not today” –
For how can I complete a thought
When like a sheep it strays away?
