A woman built a house on a piece of property that included a large field. She wanted to keep the hay mowed and preserve the field, but had no use for the hay herself. She approached a neighbor with haying equipment.
“Will you hay my field?” she said.
“No,” he said. “I can’t.”
“Why not?”
“The Hendersons been haying that field for a 100 years. It won’t do for me to take over another man’s job. Old Henderson won’t do a very good job though.”
The neighbor would not be persuaded, so the owner went to Old Henderson, and presently he hayed the field.
When she saw the neighbor again, he commented that Old Henderson had done a piss poor job, just as he’d warned her.
She sputtered.
He said, “It’s all right. Someone’s got to keep him busy.”
There’s some logic to this somewhere, if you don’t think too hard about it.
