• "A dog has no use for fancy cars or big homes or
  designer clothes. Status symbol means nothing to
  him. A waterlogged stick will do just fine. A dog
  judges others not by their color or creed or
  class but by who they are inside. A dog doesn't
  care if you are rich or poor, educated or
  illiterate, clever or dull. Give him your heart
  and he will give you his. It was really quite
  simple, and yet we humans, so much wiser and more
  sophisticated, have always had trouble figuring
  out what really counts and what does not.
