Maybe you already know it.
I didn’t until recently.
The moon is receding from the earth
at the same rate our finger nails grow.
That isn’t much
but by the time
our great grand children’s nails
have grown as much as ours
it might begin to be noticeable.
If I were in charge of this receding
I would prefer it to be
at the rate our toe nails grow.
What I would really like is
for my toe nails to stop growing.
They have been most difficult to reach
since I’ve become ninety.
