Perry's Index to the Aesopica
Fables exist in many versions; here is one version in English:
THE DONKEY, THE DOG AND THE LETTER
A donkey and a dog were journeying together when they found a sealed letter
on the ground. The donkey took the letter, broke the seals, and opened it. The
donkey then began to read the letter aloud, while the dog sat there listening.
The letter happened to be about food, that is, about barley and straw and hay.
As the donkey was reading, the dog grew impatient and finally he said to the
donkey, 'You can skip that part, my dear; perhaps further down you will find
some information about meat and bones.' The donkey scanned the rest of the letter
but he didn't find what the dog was looking for. The dog then said to the donkey,
'Throw it back on the ground; it has nothing to offer!'
The story shows that different people are interested in different things.
