Dangerous Liaisons

Surely, Marchioness, you do not take me to be such a novice, to imagine I could be duped in the tête-à-tête which I found you in this afternoon; or by the astonishing chance that led Danceny to your house! Not but your well-practised countenance wonderfully assumed a calm serenity of expression; or that you, by the most trifling word, betrayed, which sometimes happens, the least disorder or uneasiness. I will even allow your submissive looks served you eminently; and could they have made themselves as well credited as readily understood, far from having or harbouring the least suspicion, I should not at all have doubted the great vexation this troublesome trio gave you. But to display to greater advantage those extraordinary talents, to ensure the success you promised yourself, to carry on the deception you intended, you should have formed your inexperienced lover with more care.

Since you have begun to educate youth, you should teach your pupils not to blush or be disconcerted at a little raillery; not to deny so warmly for one woman, the same charge which they so faintly excuse themselves in for all others; teach them also to learn to hear encomiums on their mistress, without enhancing them.
