The reason why people are so cold-hearted is that they don't want to get into trouble. Life is becoming busy nowadays. There are always too many things to deal with. People don't want to put their energy on something that is none of their own business. It seems that people are becoming more selfish. But should we blame them? I don't think so. They have already got too much burden in their life, so it is reasonable that they only think about themselves. A: I am afraid I can't agree with Candidate B. Busy life can not be the reason for people to become cold-heart-ed. The whole society is a big family. People should try to help each other. Every body will meet some trouble in their life and people should rely on each other.
