When your mother frowns at you without saying a word, you know that you have displeased her. Her displeasure is expressed through her body
language. In this way, other emotions too, are reflected through When you cross your arms, and lean away from another person to you are telling him that you want him to keep a distance, though of course, it may also mean that your arms are cold. If you look at a person in the eyes while speaking, it is a sign of honesty and straight forwardness. Looking away can mean you are lying, or that you don’t like the person. A person who shakes his legs constantly, or wets his lips is under stress. A person who leans towards you with clenched fists is quite likely to attract you! So you see, understanding body language helps you to understand the emotions of other people better.
