Enemies multiply kisses

Have you ever been smooth-talked into buying something you really didn't need? During a period of 6 months we were visited by two of the most smooth-talking door-to-door salesmen on the face of the planet. The proverb says, "Wounds from a friend can be trusted, but an enemy multiplies kisses" (Proverbs 27:6). I'm not sure those salesmen are enemies. But they sure did kiss up to us.
