True, ALTHOUGH... hm - lets see if I can find the words: Ok.
   Going COMPLETELY hypothetical: IF... ...that which is "you" is
   really everything you've ever experienced, seen, heard, thought,
   all rolled into a thing you call your "me" AND.... ...it
   includes everything you WILL ever be aware-of in your lifetime
   and incorporate into you.... AND... ...you can't see my private
   mind and you are never privy to it in its entirety... ...THEN
   it's theoretically POSSIBLE that I am what you aren't, because
   that which is "me" _could_ incorporate everything in the entire
   UNIVERSE that you will never know, see, experience in any way at
   all. SO... in that sense, I *could* be everything you're not.
   But man, what a stretch that would be.
