Hands. Of all the body parts, the hands probably are used most for communicating non-verbally. Hand waves are used for greeting, beckoning, or farewell. The American 'goodbye' wave can be interpreted in many parts of Europe and Latin America as the signal for 'no.' The Italian 'goodbye' wave can be interpreted by Americans as the gesture of 'come here.' The American 'come here' gesture can be seen as an insult in most Asian countries where they use it for calling an animal. Asians call others with a similar hand movement but with their palm downward.
