Honesty is the best policy.
An Ass and a Fox went into partnership and sallied out to forage for food together. They hadn’t gone far before they saw a Lion coming their way, at which they were both dreadfully frightened. But the Fox thought he saw a way of saving his own skin, and went boldly up to the Lion and whispered in his ear, “I’ll manage that you shall get hold of the Ass without the trouble of stalking him, if you’ll promise to let me go free.” The Lion agreed to this, and the Fox then rejoined his companion and contrived before long to lead him by a hidden pit, which some hunter had dug as a trap for wild animals, and into which he fell. When the Lion saw that the Ass was safely caught and couldn’t get away, it was to the Fox that he first turned his attention, and he soon finished him off, and then at his leisure proceeded to feast upon the Ass.
Betray a friend, and you’ll often find you have ruined yourself.
A Lion asleep in his lair was waked up by a Mouse running over his face. Losing his temper he seized it with his paw and was about to kill it. The Mouse, terrified, piteously entreated him to spare its life. “Please let me go,” it cried, “and one day I will repay you for your kindness.” The idea of so insignificant a creature ever being able to do anything for him amused the Lion so much that he laughed aloud, and good-humouredly let it go. But the Mouse’s chance came, after all. One day the Lion got entangled in a net which had been spread for game by some hunters, and the Mouse heard and recognised his roars of anger and ran to the spot. Without more ado it set to work to gnaw the ropes with its teeth, and succeeded before long in setting the Lion free. “There!” said the Mouse, “you laughed at me when I promised I would repay you: but now you see, even a Mouse can help a Lion.”
