Wouldn't you love to be able to look into people's hearts or minds and to know exactly what they are really thinking or feeling? Well, that doesn't happen you can't do that. You really won't know deep down what's going on in people. Not even psychologists know.

One of the major differences between people and other living animals is that people have feelings and thoughts. Another difference is that they can hide those feelings and thoughts and put on a brave front.

A person in the courtrooom who is being accused of a terrible crime might show that he is brave and bold in order to give the impression that he is not guilty. Sometimes it does work.

A person might be challanged to do something or to act in a certain way by a tough guy and that too might have an impact and it might work. Your perception of their feelings will affect the way that you act towards them, but their feelings may remain a secret and you may never know what is really going on.
