Context

“It is full of fine oats, which I have left untouched for you, as you are a friend whom I would love to hear enjoying good eating.” The Horse replied, “If oats had been the food of wolves, you would never have indulged your ears at the cost of your belly.” Men of evil reputation, when they perform a good deed, fail to get credit for it. The Brother and the Sister A FATHER had one son and one daughter, the former remarkable for his good looks, the latter for her extraordinary ugliness. While they were playing one day as children, they happened by chance to look together into a mirror that was placed on their mother’s chair.” source
