When we speak something, it is our body and its gestures that help in conveying the desired message effectively and easily. Sometimes we don’t utter a single word, and yet we are able to communicate a lot. It is because our body parts, especially our facial expressions combined with various other gestures, speak a language of their own, which we call body language. It is not always that what we speak is really what we intend to say. Most of the time, while speaking, we do actually act. Our acting involves varying our speech and body gestures to suit different circumstances which we come across on different occasions in our daily life.
The whole world is like a stage where we all are mere performers. That is why we talk and behave differently with different people. While living in the same environment with a similar set of people for long, one tends to become stereotyped in one’s behaviour. And, in that case, it is highly possible that our acquaintances or people who interact with us regularly can easily understand our body language. Frankly speaking, body language is the only language which is common all over the world. Everybody can easily communicate through this language. But one must learn to interpret it precisely; otherwise, misinterpretation of body gestures could create lot of problems.
