I have posted at one time the question DH (a woodworker) asked: "When do you think you will use up all that fabric?"

And I calmly replied: "When your last scrap of wood is gone . . . "

He hasn't said a thing again.

"When your truck disappears into rust and ruin."
"When you break your last Craftsman."
"When you've exposed your last roll of Kodachrome."
"When you've used our last quart of oil."
