Article: Most people call it "body language" -- the clues to the meaning that we get from gesture, facial expressions, posture -- everything that isn't spoken.Experts call it "nonverbal communication," but it means the same thing: a second source of human communication that is often more reliable to understanding what is really going on than the words themselves. Understanding body language is important to success, whether in the business world or in our personal lives.However, most of our ideas about body language are wrong, according to modern communication research. There is a belief that people with shifty eyes are probably lying.As Paul Ekman says, "When we asked people how they could tell if someone was lying, too much blinking and shifty eyes were the winners.But sometimes people act like that because they are shy.Liars pretend to be calm in order not to be caught. Ekman goes on to argue against such a wrong belief.Although this kind of body language is probably an expression of nervousness, it is not always because the person is lying.Shyness can, for example, make people shift their eyes.To understand what someone's behavior means, you have to watch them carefully. There is also a belief that when meeting someone, the more eye contact , the better.As a result people would like to make initial contact in formal situations, like a job interview, by staring fixedly at the other human.Yet Ekman points out that most of us are comfortable with eye contact lasting a few seconds, but any eye contact that is longer than that can make us nervous. In short, you must carefully consider the speaker and the speaking environment.Experts suggest that unless you know about someone's basic communication style, you will have little hope in understanding their true feelings through body language.In other words, body language carries important but not always true messages.

Article: Paul received an automobile from his brother as a Christmas present. On Christmas Eve when Paul came out of his office, a street boy was walking around the shiny new car, admiring it. "Is this your car, Mister?" he asked. Paul nodded. "My brother gave it to me for Christmas." The boy was astonished. "You mean your brother gave it to you and it didn't cost you anything? Boy, I wish...." He hesitated. Of course Paul knew what he was going to wish for. He was going to wish he had a brother like that. But what the kid said made Paul quite surprised. "I wish," the boy went on, "that I could be a brother like that." Paul looked at the boy in astonishment, and then impulsively he added, "Would you like to take a ride in my automobile?" "Oh, yes, I'd love that." After a short ride, the boy turned and with his eyes shining, said, "Mister, would you mind driving in front of my house?" Paul smiled a little. He thought he knew what the he wanted. He wanted to show his neighbors that he could ride home in a big automobile. But Paul was wrong again. "Will you stop where those two steps are?" the boy asked. He ran up the steps. Then after a little while Paul saw him coming back, but he was not coming fast. He was carrying his little crippled brother. He sat him down on the bottom step, then sort of squeezed up against him and pointed to the car. "There _ is, Buddy, just like I told you upstairs. His brother gave it to him for Christmas and it didn't cost him a cent. And some day I'm going to give you one just like it... then you can see for yourself all the pretty things in the Christmas windows that I've been trying to tell you about."
