阅读理解。

     I went home one Saturday afternoon in the autumn of 1993 to get some work done in the garden. While

sweeping leaves on the ground, my five-year-old son Nick came over and asked me to write something on

a piece of paper to make a sign for him.

     "What for?" I asked.

     "I'm going to sell some of my stones," he answered.

     Nick was fascinated with stones and had collected many stones from all over.

     "I'm too busy to do that for you. Go and ask your mum for help," I said.

     A short time later, Nick, returned with a sign, reading, "Stones, One Dollar Each". He took the sign, a

small chair and 4 of his best stones and walked to the road in front of our garden. There he put the stones

in a line and sat down on the chair.

     After half an hour, nobody passed by. I walked to him and asked him to go back, but he didn't.

     Another half hour later, a small car came down the road. I watched as Nick stood up, holding his sign up.

A woman rolled down a window and read the sign. I couldn't hear their talk, but I saw the woman turn to the

driver and the man reach for his pocket.

     I sat in the yard, as Nick ran to me. Waving the dollar, he shouted, "I told you I could sell one stone for

a dollar-if you believe in yourself, you can do anything."
