this non-verbal communication is possible because we use body language, unconsciously accept it and respond to it.
body language is an important part of any interaction, so every person should develop an ability to read other people signals and interpret them so as to be aware of their unconscious feelings and emotions.
body language isn`t always just one movement. very often it is more than one, but you can be assured that if your non-verbal signals are out of kilter with your spoken message, the people listening to you will feel uncomfortable, or may not believe, or may not be interested, etc.
