Body language is a personal thing. It tells a lot about a person's character, such as whether he shows respect for others to whom he is talking, and whether he pays proper attention to someone else's ideas. Think about your own body language. Be conscious of it. For example: when you meet someone, don't stand too close. An uncomfortable closeness is very annoying to the other person, so keep your physical distance, or he will have to keep backing off from. you. A minimum of two feet will do it. Some of the ways in which your body will tell the other person you are listening intently are these. You sit attentively in your chair. If you slump down on your backbone, your legs straight out in front of you, your body is saying, "I don't care what you are saying and frankly, you bore me." You watch the face of the person speaking and do not let your eyes roam randomly around the room. It's polite to give the person speaking your full attention. You keep your leg still, not continuously shifting your position or crossing and uncrossing your knees. The latter body language signifies either aching joints or the fact that you can hardly wait to get away. Letting your knee bounce up and down continuously also denotes boredom with the present company, which is the way you may feel, but you should certainly disguise that fact.
