I’m pretty sure it was,
A Social Study by Michael Balwin
which has appeaed on a couple of books of short stories and poems over the years.

Don’t know anything about him though

While my mother ate her heart out
and my father chewed the chairs
my sister worked in a factory
calmly degutting pears.

The green pears like spinach
the yellow pears liks sick
she gently disembowled them
with a deft little flick.

She never seemed to worry,
Or share the family fears,
For thoughts like bees were buzing
Between her golden ears.

She jilted a tin carpenter,
And then a lebeller’s mate
And finally she married
The man who nails the crate

They had two lovely children
called Dorothy and Clem
They’re hanging her tomorrow
for calmly degutting them.
