nonverbal communication

In countries such as Japan, China, India, and Iran there are gestures that convey different meanings in comparison with gestures we use in the United States. Find an example of a gesture or non-verbal behavior (holding hands, for example) from any other country of the world that you did not know about. Provide a link and/or explain the gesture, the meaning, and compare (why or why not we interpret it differently or it does not exist in the United States)
