MARLEY AND ME
LAB POPULARITY
• "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.
