ASKING FOR FOOD IN NY

This video shows us how a man asks for food to people "with money", and they reject him and one of them is very rude about it. Then the same man gives sevral slices of pizza to a homeless and then 20 minutes later, the guy ask him if he if can have a slice and the homeless says yes, and that´s beacuase the homeless knows the pain of being hungry and in a way that transforms people, because they have suffer, and the video made me ask myself if the suffering and the pain is necessary to make the people conscious about the situation of others.
