A cheerful, easy, open countenance will make fools think you a good-natured man, and make designing men think you an undesigning one.
Lord ChesterfieldYou should not only have attention to everything, but a quickness of attention, so as to observe at once all the people in the room--their motions, their looks and their words--and yet without staring at them and seeming to be an observer.
Lord ChesterfieldMen are much more unwilling to have their weaknesses and their imperfections known, than their crimes; and, if you hint to a man that you think him silly, ignorant, or even ill-bred or awkward, he will hate you more, and longer, than if you tell him plainly that you think him a rogue.
Lord Chesterfield
