It's reported frequently that passerbys do nothing but stand and see when old men fall.People even get numb about this.How it happen?Why people become this selfish and unsympathetic?In my opinion,many factors lead to such an situation.In today's world ,money always first before other things.People study ,work for money,country also puts GDP on top. With the ecnomic grows quickly,mental education was ignored. Meanwhile,some negative news hurt people's compassion that the old man pretend to fall on purpose to inculpate innocent people who stretch out his arms to help for money. It's horrible....Sometimes I asked myself,if I were there,what would I do? help or not?what if it's a trap? I don't know the answer.what will you guys do?
