Were you to converse with a king, you ought to be as easy and unembarrassed as with your own valet de chambre; but yet, every look, word and action, should imply the utmost respect. What would be proper and well-bred with others, much your superiors, would be absurd and ill-bred with one so very much so. You must wait till you are spoken to; you must receive, not give, the subject of conversation; and you must even take care that the given subject of such conversation do not lead you into any impropriety. The art would be to carry it, if possible, to some indirect flattery; such as commending those virtues in some other person, in which that prince either thinks he does, or at least would be thought by others to excel. Almost the same precautions are necessary to be used with ministers, generals, etc., who expect to be treated with very near the same respect as their masters, and commonly deserve it better. There is, however, this difference, that one may begin the conversation with them, if on their side it should happen to drop, provided one does not carry it to any subject upon which it is improper either for them to speak, or be spoken to. In these two cases, certain attitudes and actions would be extremely absurd, because too easy, and consequently disrespectful. As, for instance, if you were to put your arms across in your bosom, twirl your snuff-box, trample with your feet, scratch your head, etc., it would be shockingly ill-bred in that company; and, indeed, not extremely well-bred in any other. The great difficulty in those cases, though a very surmountable one by attention and custom, is to join perfect inward ease with perfect outward respect.
