THE DONKEY AND THE HORSE

A horse who was overly proud of his elegant trappings happened to run into a donkey. The donkey was worn out with work and slow to make way for the approaching horse. 'I am tempted to smash you to pieces with my hooves,' said the horse. The donkey said nothing and only groaned, calling upon the gods to take note of his suffering. Not long afterwards, the horse, now a broken down wreck from his life on the race track, was sent to work on a farm. When the donkey saw the horse carrying a load of manure, he laughed and said, 'What has happened to you, who were once so proud of your elegant trappings? Time has reduced you to the wretchedness you formerly scorned!'
When prosperous folk are inclined to look down on others, they should hesitate, mindful of the fact that nobody knows what the future may bring.

In Perry 357, the donkey envies the horse, but after the horse is taken away to war where he is badly wounded, the donkey realizes that it is not so bad to be a donkey. In Perry 565, the elegant race horse makes fun of the hard-working donkey, but later on, when the horse's racing career is over, he is made to haul manure, and the donkey makes fun of the horse.
