A self-important fly was sitting on a wagon-pole, shouting at the mule who pulled the wagon.
"What a slowpoke you are!" said the fly. "Why don't you hurry up? If you don't hurry up, I will bite you!"
The mule scoffed at the fly. "The only thing I care about is the whip in the hand of my driver," said the mule. "If he is satisfied with my progress, that is good enough for me. I don't like the sting of his whip, but as for your bite, I don't care about that. You are nothing but a little insect!"
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 255 in the book, which is Perry 498.
