Interpreting Body Language
Every person has a unique body language. Although silence usually denotes that an individual is reserved and relaxed, some people keep their anger within themselves and stay quiet. (This is very unhealthy because rage kept up inside can explode furiously anytime, causing serious casualties). A wide open mouth may indicate shock or astonishment for one person, while another person who performs this gesture could just be concentrating intently on a task hes doing. Constantly touching the mouth may indicate lying, although the real reason might just be that the mouth is itching.
One way to overcome this dilemma is to watch out for other signals that jive with the body language being exhibited. For example, you can confirm if a person is really nervous if he exhibits many of the qualities of nervousness described above. Judgment based on one or two gestures only may not be accurate enough, although they can be dependable. Be aware of the body language, but also combine your observations with the spoken words to get more hints regarding the inner feelings of another. Use this power to your advantage.
