Aesop's Fables (1884)
121. The Dog and the Hare.
A Hound, having started a Hare on the hill-side, pursued her for some distance, at one time biting her with his teeth as if he would take her life, and at another time fawning upon her, as if in play with another dog. The Hare said to him: "I wish you would act sincerely by me, and show yourself in your true colors. If you are a friend, why do you bite me so hard? If an enemy, why do you fawn on me?"
They are no friends whom you know not whether to trust or to distrust.
