Henry was a carpenter（木匠）of our village．Once I asked him to make a dining table for my wife．He made it just the right size to fill the space between the two windows．When I arrived home that evening,Henry was drinking a cup of tea and writing out his bill for his work．
　　My wife said to me,quietly,"That's his ninth cup of tea today．" But she said loudly,"It's a beautiful table,dear,isn't it?"
　　"I won't decide about that until I see that bill．" I said．
　　Henry laughed and gave me his hill for the work．It said：

One dining table June 10,1995
Cost of wood 17.00
Paint（油漆） 1.50
Work,8 hours（1 an hour） 8.00

　　"Me too,",said Henry．"You wait--it'll be a bit hotter by the end of the month．"
　　"Yes．Hotter--and more expensive．Dining tables will be 20 more expensive on June 30th,won't they,Henry?"
　　Henry looked hard at me for half a minute．There was a little smile in his two blue eyes．I gave his ill back to him．
