A thief cannot be trusted, even by another thief.
The Two Frogs.
Two frogs dwelt in the same pool. The pool being dried up under the summer's heat, they left it and set out together for another home. As they went along they chanced to pass a deep well, amply supplied with water, on seeing which, one of the Frogs said to the other: "Let us descend and make our abode in this well." The other replied with greater caution: "But suppose the water should fail us, how can we get out again from so great a depth?"
Do nothing without a regard to the consequences.
The Vine and the Goat.
A Vine was luxuriant in the time of vintage with leaves and grapes. A Goat, passing by, nibbled its young tendrils and its leaves. The Vine said: "Why do you thus injure me and crop my leaves? Is there no young grass left? But I shall not have to wait long for my just revenge; for if you now crop my leaves, and cut me down to my root, I shall provide the wine to pour over you when you are led as a victim to the sacrifice."
