A Farmer walked through his field one cold winter morning. Do not be frightened, children, said the Mother Lark. Why are you doing that? asked the Fox at last with a grin. If I should bring you a drink, it would only serve to wash me down your throat. One day he even went so far as to leave his flock in the Wolf's care while he went on an errand. The Goat thought the Fox had gone down to drink, and so he asked if the water was good. When that Lion leaves, I'll teach you a lesson you won't forget.
Do not expect constancy in others if you have none yourself.
