Knees
A knee is a certain kind of construction,
intended to flex and support.
If you were a carpenter or prosthetist
and built such a thing you’d call it a knee.
I have two made in the last century
By God when He was perhaps at His peak.
They’re getting old, and less flexible,
ailing, sore, complaining.
I force them, sitting on them, saying:
Be knees, you knees. Be knees.
