Flatterers
Flatterers are cats that lick before and scratch behind.
—Anonymous
For as a wolf resembles a dog, so doth a flatterer a friend. A flatterer is compared to an ape, who, because she can not defend the house like a dog, labour as an ox, or bear burdens as a horse, doth therefore yet play tricks, and provoke laughter.
—Sir Walter Raleigh
