Thomas Nashe quotes
"A traveler must have the back of an ass to bear all, a tongue like the tail of a dog to flatter all, the mouth of a hog to eat what is set before him, the ear of a merchant to hear all and say nothing."
He fishes well who uses a golden hook.
Be on your guard against a silent dog and still water.
"A traveler must have the back of an ass to bear all, a tongue like the tail of a dog to flatter all, the mouth of a hog to eat what is set before him, the ear of a merchant to hear all and say nothing."
