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.... 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.
Lord ChesterfieldThere are people who indulge themselves in a sort of lying, which they reckon innocent, and which in one sense is so; for it hurtsnobody but themselves. This sort of lying is the spurious offspring of vanity, begotten upon folly.
Lord ChesterfieldNothing sharpens the arrow of sarcasm so keenly as the courtesy that polishes it; no reproach is like that we clothe with a smile and present with a bow.
