Fable 16 - The Goat and the Donkey

A man kept a goat and a donkey. The goat became jealous of the donkey, because it was so well fed. So she said to him:
‘What with turning the millstone and all the burdens you carry, your life is just a torment without end.’
She advised him to pretend to have epilepsy and to fall into a hole in order to get some rest. They donkey followed her advice,
fell down and was badly bruised all over. His master went to get the vet and asked him for a remedy for these injuries. The vet
prescribed an infusion of goats’ lung; this remedy would surely restore him to health. As a result, the man sacrificed the
goat to cure the donkey.

Whosoever schemes against others owes his own misfortune to himself.
