They say that during an assembly in Athens, Demosthenes was prevented from making his speech, so he told the audience he wanted to say just a few words.
When the audience had fallen silent, Demosthenes began his tale. 'It was summertime, and a young man had hired a donkey to take him from Athens to Megara. At midday, when the sun was blazing hot, the young man and the donkey's driver both wanted to sit in the donkey's shadow.
They began to jostle one another, fighting for the spot in the shade. The driver maintained that the man had rented the donkey but not his shadow, while the young man claimed that he had rented both the donkey and all the rights thereto.'
Having told this much of the story, Demosthenes then turned his back on the audience and began to walk away.
The Athenians shouted at him to stop and begged him to finish the story.
'Indeed!' said Demosthenes. 'You want to hear all about the donkey's shadow, but you refuse to pay attention when someone talks to you about serious matters!'
