Body language” is a kind of nonverbal communication with the richest meanings and greatest function. Like verbal language, it is also a part of culture. But not all body languages mean the same thing in different cultures. Different people have different ways of making nonverbal communication. For example, different people have different ideas about the proper distance when conversing with others, also they lay much emphasis on the appropriateness of physical contact. One could draw up quite a list of “rules” about eye contact: to look or not to look, when to look and how long to look, who and who not to look at.
