There was a traveler making a long journey, and he had grown hungry along the way.
"O Hermes," he prayed, "please help me! With your divine power, bring me good luck so that I can find something to eat. I promise to give you half of whatever I find!"
The traveler then found a bag of almonds lying on the road. He ate the nuts, and afterwards offered the shells to Hermes.
"Behold, Hermes," the traveler said solemnly, "here is half, just as I promised."
A greedy person will even cheat the gods in order to get what he wants.
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 788 in the book, which is Perry 178.
