because it's still National Poetry Month, have some Phyllis McGinley

Apologia

When I and the world
Were greener and fitter,
Many a bitter
Stone I hurled.
Many a curse
I used to pitch
At the universe,
Being so rich
I had goods to spare;
Could afford to notice
The blight on the lotus,
The worm in the pear.

But needier grown
(If little wiser)
Now, like a miser,
All that I own
I celebrate
Shamefacedly--
The pear on my plate,
The fruit on my tree,
Though sour and small;
Give, willy-nilly,
Thanks for the lily,
Spot and all.
