"What′ s up, Simon You don′ t look very happy." "The customers always prefer Debbie to me. I don′ t understand why." "I do. It′ s the way you communicate." "How can that be" Simon asked. "I don′ t even get a chance to speak to them." "Speech is not the only method of communication. Your body language is important, too." "What kind of language is that" "It′s the way you stand and sit. It′s your gestures and the expression on your face and in youreyes. Your whole appearance communicates things. You often rest your head on our hand. You don′t look up. You never smile. So you don′ t make a good impression on people." "But look at Debbie. She makes eye contact with the customers. She′s holding her head up. She smiles, that′ s why the customers go to her and not to you."
