Oh I can _swear_ I read that somewhere about the "lost in the
  woods" thing... but not its connection to "I am" - I need to
  brush up on my PIE. I know I'm going to end up learning all
  about it some day; it's a natural direction. Yes, if you can
  find the metaphorical connections to concepts, all of
  communications just opens WIDE! Every sentence has meanings even
  hidden from those that write and say them, but YOU'LL see them.
  Very physical manifestations of concepts leap into the mind.
  Yes, please share any metaphorical stuff you find - PIE or
  anywhere - as I think it's the best way to master sensemaking in
  any situation on any topic. == and yes - I remember that
  episode. With a lifelong interest in linguistics, etymology and
  sensemaking in general, I was cheering the whole time. It's like
  the episode was made for me.
