All humans have one thing in common that they can feel their feelings as well as the feelings of other human beings. This is what differentiates us from animals. This is the thing which is missing in animals. Still having this power of feeling. We often forget to use it. Many times we do ignore the feelings of others and just see our own feelings. That's not good I think so. We should understand the feelings of other human beings too. In that way, we can understand the other person's perspective also.
