Before Avatar

I found this passage intriguing, especially since I enjoyed the movie Avatar so very much.  It is a passage from The Fifth Discipline Fieldbook as quoted in Susan Scott's Fierce Conversations:  Achieving Success at Work & in Life, One Conversation at a Time:

Among the tribes of northern Natal in South Africa, the most common greeting, equivalent to "hello" in English, is the expression:  "sawu bona."  It literally means, "I see you."  If you are a member of the tribe, you might reply by saying "sikhona" or "I am here."  The order of the exchange is important:  until you see me, I do not exist.  It's as if, when you see me, you bring me into existence.

Avatar director and writer, James Cameron, had a little inspiration it seems... :)
