Why do we have to help each other a variety of reasons, and each reason may be based on individual circumstances. The first reason is happy to be helping others, for example, when we see people dropping wallet. We kept going to him. We would be happy to help. The second reason we feel compassion for example, if we see a blind man was crossing the street, but no one to help him, we took pity and help him take over the streets. The final reason I asked help. For example, people may not get the flip. He may ask us to walk past her to help him up. We had to help him. The reason is that we help each other, probably because we are happy to help those who may be suffering because of the poor may be forced by circumstances to others for help.
