The Traveler and His Dog
A Traveler about to set out on a journey saw his Dog stand at the door stretching himself. He asked him sharply: Why do you stand there gaping? Everything is ready but you, so come with me instantly. The Dog, wagging his tail, replied: O, master! I am quite ready; it is you for whom I am waiting.
The loiterer often blames delay on his more active friend.
