　　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 bill for the work． It said：

　　When I was looking at the bill, Henry said, “It's been a fine day, isn't it?Quite sunny．”

　　“Yes,” I said．“I'm glad it is only the 10th of June．”

　　“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 bill back to him．

　　“If it isn't too much trouble, Henry,” I said, “Please add it up again．You can forget the date．”

　　I paid him 26.50 and he was happy to get it．
