A well-dressed man entered a famous jewelry shop. He explained that he wished to buy a pearl for his wife’s birthday and the price did not matter, since business had been very good for him that year. After examining a number of beautiful expensive pearls, he chose a nice black one that cost $ 5,000. He paid for the pearl in cash, shook hands with the jeweler, and left. A few days later the man returned and said that his wife liked the pearl so much that she wanted another one just like it. He had to buy one of exactly the same size and quality, as she wanted to have a pair of earrings made. “Can you give me any advice on how to get such a pearl?” said the man. The jeweler regretfully replied, “I would say it’s nearly impossible to find an exact one like that pearl.” The rich man insisted that the jeweler advertise in the newspapers, offered $ 25,000 for the matching pearl. Many people answered the ad but nobody had a pearl that was just right. Just when the jeweler had given up, a little old lady came in to his shop. To his great surprise, she pulled the perfect pearl from her purse. “I don’t like to part with it,” she said sadly, “I inherited it from my mother, and my mother inherited it from hers. But I really need money.” The jeweler was quick to pay her before she changed her mind. Then he called the rich man’s hotel to tell him the good news. The man, however, was nowhere to be found.
