A young couple move into a new neighbourhood. The next morning, while they are eating breakfast, the young woman sees her neighbour hanging the washing outside.

"That washing isn't very clean," she said. "She doesn't know how to wash. Either that or she needs better detergent."

Her husband looked on, but remained quiet.

Every time her neighbour would hang the washing out, the young woman would make the same comments.

About a month later, the woman was surprised to see a nice clean wash on the line and said, "Look, she's learned how to wash. I wonder who showed her what to do."

The husband looked up and said: "I got up early this morning and cleaned our windows."
