The Fox And the Grapes
A hungry Fox saw some fine bunches of Grapes hanging from a vine that was trained along a high trellis, and did his best to reach them by jumping as high as he could into the air. But it was all in vain, for they were just out of reach: so he gave up trying, and walked away with an air of dignity and unconcern, remarking, "I thought those Grapes were ripe, but I see now they are quite sour."
The Goose That Laid the Golden Eggs
A Man and his Wife had the good fortune to possess a Goose which laid a Golden Egg every day. Lucky though they were, they soon began to think they were not getting rich fast enough, and, imagining the bird must be made of gold inside, they decided to kill it in order to secure the whole store of precious metal at once. But when they cut it open they found it was just like any other goose. Thus, they neither got rich all at once, as they had hoped, nor enjoyed any longer the daily addition to their wealth.
Much wants more and loses all.
The Cat And the Mice
There was once a house that was overrun with Mice. A Cat heard of this, and said to herself, "That's the place for me," and off she went and took up her quarters in the house, and caught the Mice one by one and ate them. At last the Mice could stand it no longer, and they determined to take to their holes and stay there. "That's awkward," said the Cat to herself: "the only thing to do is to coax them out by a trick." So she considered a while, and then climbed up the wall and let herself hang down by her hind legs from a peg, and pretended to be dead. By and by a Mouse peeped out and saw the Cat hanging there. "Aha!" it cried, "you're very clever, madam, no doubt: but you may turn yourself into a bag of meal hanging there, if you like, yet you won't catch us coming anywhere near you."
If you are wise you won't be deceived by the innocent airs of those whom you have once found to be dangerous.
