Last week, I met a stranger who seemed to be losing. I offered to guide him to a place he wanted to go to, but to my surprise, he refused my offer to helping. I asked him why not. He told me that he was afraid I would ask him money if I helped him in this way. Then I fell into deep thoughts: Was it money which came between us? I agree that money is become more and more important in our society, and it should not be everything. We should try my best to help others and trust each other. If everyone does this, our society will be better and better.
