One day, a rich man and a businessman met in a restaurant. They both ordered soup for their lunch. When it was brought, the rich man tasted it, but the soup was so hot that he burned his mouth and had tears in his eyes. The businessman asked him why he was crying. The rich man didn't want to tell the truth, so he told a lie. "Sir, I had a brother who was killed last year. I was thinking of his death, and that made me cry." The businessman believed his story and began to eat his soup. He also burned his mouth and had tears in his eyes. The rich man noticed it and asked the business man, "Sir, why are you crying?" The businessman answered, "Oh, I'm crying, because you were not killed together with your brother."
