     Some time ago I discovered that one of my chairs had a broken leg. I didn't think there would be any

difficulty in getting it mended, as there are a whole lot of antique (古董) shops near my home. So I left

home one morning carrying the chair with me. I went into the first shop expecting a friendly reception.  I

was quite wrong.  The man wouldn't even look at my chair.

     The second shop,  though slightly more polite,  was just the same,  and the third and the fourth- so I

decided that my approach must be wrong. I entered the fifth shop with a plan in my mind.  I placed the

chair on the floor and said to the shopkeeper,  "Would you like to buy a chair?" "Twenty pounds," I

said.  "OK,"he said. "l'll give you twenty pounds." "It's got a slightly broken leg," I said.  "Yes, I saw that.  

It's nothing."

     Everything was going according to the plan and I was getting excited.  "What will you do with it?" I

asked.  "Oh, it will be easy to sell once the repair is done. " "I'll buy it," I said.  "What do you mean?

You've just sold it to me," he said.  "Yes,  I know but I've changed my mind.  I am sorry. I'll give you

twenty-seven pounds for it."  " You must be crazy," he said. Then, suddenly the penny dropped.  "I

know what you want. You want me to repair your chair."

     "You're right," I said.  "And what would you have done if I had walked in and said,   'Would you

mend this chair for me?'" "I wouldn't have agreed to do it," he said.  "We don't do repairs, not enough

money in it and too much trouble.  But l'll mend this for you.  Shall we say for a fiver?" He was a very

nice man and was greatly amused by the whole thing.
