His sympathetic wife

A businessman dragged himself home and barely made it to his chair before he dropped exhausted.

His sympathetic wife was right there with a tall cool drink and a comforting word.

"My, you look tired," she said.

"You must have had a hard day today. What happened to make you so exhausted?"

"It was terrible," her husband said. "The computer broke down and all of us had to do our own thinking."
