Fable XVI The Dog and the Crocodile
It is ever dangerous to be long conversant with persons of a bad character.
We can never be too carefully guarded against a connection with persons of an ill character.
As a dog was coursing on the banks of the Nile, he grew thirsty; but fearing to be seized by the monsters of that river, he would not stop to satiate his draught, but lapped as he ran. A Crocodile, raising his head above the surface of the water, asked him, why he was in such a hurry. He had often, he said, wished for his acquaintance, and should be glad to embrace the present opportunity. You do me great honour, returned the Dog, but it is to avoid such companions as you that I am in so much haste.
