Body language

Body language is an important part of communication, which can help you to communicate well and understand other people. For this reason it is very useful to learn body language. Here are some movements, which are the most common.
First, don’t be afraid to take up some space – taking up space, for example, sitting or standing with your legs apart signals self-confidence and that you are comfortable. If you are listening to a person it is recommended to nod, it shows that you are listening to him, but don't overdo it, it can look stupid. And another important thing is not to stand too close to a person when your talking to him, because you are interrupting his private space, which is impolite and may signal rudeness.
It is also important to understand when other person is lying. persons who are laying may be very anxious. Many of us have hidden anxiety signals. For example: Biting the inside of the mouth, patting head, hands in pockets. Anxiety may be displaced into actions such as fidgeting, moving around the place or paying attention to unusual places.
Here are only few movement mentioned, but there are hundreds of movements to understand. However, we have to be critical because, for example if a persons sits with his arms crossed on his chest it could also mean that he is just cold.
