A few people were having dinner in a restaurant. While they were eating fish, they began to tell stories about finding valuable stones inside fish. An old man said at last. “ Now I'm going to tell you a true story of my own. When I was young, I worked in a large company in New York. As is usual with other young people, I fell in love with a pretty girl. Soon, we were engaged. Two months before our marriage, I was suddenly sent to Washington on business. My stay was a bit longer than I had expected. At last my work was done and I left for home. Before I left Washington, I bought a nice diamond ring for my sweet ­ heart. On my way to New York, I was looking of my sweet ­ heart's getting married to another man. I was so sad that I threw the diamond ring into the water. A few days later, when I was eating, I bit on something very hard, what do you think it was ?”“ The diamond ring. ” shouted his friends. “ No ,” said the old man sadly, “ It was fish bone. ”
