I talked to one once also. He was asking for food or money while people were passing him. Many of the people gave money to the guy who was break dancing 20 feet away but gave nothing more than a glimpse to him. Me and my friend stopped and talked to him. He was really nice and so sweet. His shoes were dirty and torn, his clothes were the same. I gave him my lunch (plus side for working at subway :P) and she gave him some money.
