  > We're really really different, we have the same viewpoint of the world
  > and where it's going, different approach to it.  He's more bothered
  > probably about the end of society and mankind and stuff than I am
  > because he wants to do something about it.  And I, I'm just kind of a
  > laid back zen buddhist and just say well, y'know I'll do what I can,
  > and, so be it.
