Our village carpenter (木匠) , John, came one day and made a dining table for my wife. He made it just the right size for the space between the two windows. When I got home that evening, John was drinking a cup of tea and writing out his bill for the job.

My wife said to me quietly,“That’s his ninth cup of tea today. ”But she said, in a loud voice,“It’s a beautiful table, dear, isn’t it？”

“I’ll decide about that when I see the bill. ”I said.

John laughed and gave me his bill for the work. I read:

One dining table                        10 November, 1998

Cost of wood                            $17. 00

Paint                                   $1. 50

Work, 8 hours ( $1 an hour )            $8. 00

Total                                   $36. 50

When I was looking at the bill, John said, “It’s been a nice day, hasn’t it？Quite sunny. ”

“Yes. ”I said. “ I’m glad it’s only the tenth of November. ”

“Me, too. ”said John. “You wait — it’ll be a lot colder by the end of the month. ”

“Yes,colder — and more expensive! A dining table will be $20 more expensive on November 30, won’t it, John？”

John looked hard at me for half a minute. Was there a little smile in his two blue eyes？I gave his bill back to him.

“If there isn’t too much trouble, John,” I said,“please add it up again. You can forget the date…”

I paid him $26. 50 and he was happy to get it.
