While Mona was going, a boy crying in the middle of the street. She asked him why he was shouting. He told her that he lost 50 piasters which his mother had given him to buy sweets. He likes sweets and wanted to buy some. Mona and the boy looked for the money for a quarter of an hour. They didn't find anything as it was getting dark. Mona was very late and decided to go home. The little boy cried again. She gave him 50 piasters and told him to go home. He stopped crying and laughed. Suddenly, he looked sad and began to shout again. Mona asked him what made him sad again. He said, " If I hadn't lost the 50 piasters, I would have had 100 piasters ".
