A building contractor was paid by the week for a job that was to stretch over several months. He approached the owner the property and held the check he'd given. "This is two hundred dollars than we agreed ," he said.

"I know," the owner said, "But last week I you two hundred dollars, and you complained."

The contractor said, "Well, I don't an occasional mistake. But when it gets to a habit, I I have to call it to your attention."
