He lived on a street corner in Kansas City, holding out a cup and asking passers-by for money. But then, one day, his life changed.On February 9th, a kindhearted woman named Sarah Darling passed Billy Ray. She reached into her purse, took out all the coins she had and dropped them into his cup. Neither of them realized that this small generous act would change their lives.Sarah didn’t realize that she had given Billy her $4000 diamond ring with all her change until the following morning. She and her husband, Bill Krejci, rushed to see if they could find Billy. To their surprise, the homeless man was not only in the same place, he also returned the ring at once. The grateful couple paid him back for his honesty by emptying out their pockets of all the money they had.But this was just the beginning of their story. Sarah and her husband, Bill, became friends with Billy Ray. Bill Krejci, a web designer, felt that he needed to do something more for this amazingly honest man. So on February 18th, he set up a special page to raise money for him. In just three months, Billy received over $200,000. That is not enough. Billy is living with a person who is generous instead of living in the streets.
