what is body language

Body language is one of the most powerful means of communication,ofen even more powerful than spoken language.People around the world show all kinds of feelings,wishes and attitudes that they might never speak aloud.With so many cultural differences between people,it is great to have some similarities in body language.We can often be wrong about each other,so it is an amazing thing that we understand each other as well as we do.Not all cultures greet each other the same way,nor are thay comfortable in the same way with touching or distance between people.These actions are not good or bad,but are simply ways in which cultures have developed.Ihave seen,however,that cultural customs for body language are very general--nor all members of a culture behave in the same way.In general,though,studing international customs can certainly help avoid difficulties in today's world of cultural cressroads.
