Perry's Index to the Aesopica
Fables exist in many versions; here is one version in English:
THE TWO HYENAS
They say that the hyena has a double nature: for a period of time the hyena
is male, and then later on she is female. The story goes that when a male hyena
was treating a female badly, she said to him, 'Listen here: remember how things
used to be, and don't forget that I will be a male hyena the next time around!'
The fable is a lesson for someone who is temporarily in a position of authority:
people who have been judged in the past can later on be in a position to judge
their former teachers.
