With that thought the mule then began running around the meadow at top speed, tossing his head and whinnying.
But then the mule heard a donkey braying in the distance. The sound brought the mule to an abrupt halt. "Silly me!" he said. "I suppose that is my father's voice reminding me that, while my mother is a horse, my father is nothing but a donkey."
Inspired by: Mille Fabulae et Una, a collection of Latin fables that I've edited, free to read online. I am not translating the Latin here; instead, I am just telling a 100-word version of the fable.
Notes: This is fable 256 in the book, which is Perry 315.
