Analysis of Old Mules

Old mules.
Steps away.
From being sent to a pasture.
Grazing on grass for the rest,
Of their numbered days.
Prepared to race as if thoroughbreds.
One with a fictioned vision.
And the other with eyes on a future.
A future with promise,
For those much younger groomed to lead.
But listen they do,
To an old mule.
With nothing more to do to prove,
It is only an ego to feed it.
Left to assume and believe,
This race to run has already been won.
Rather or not,
Neither one is fit to cross the finish line!
