" Good-bye, my fair friend; beware of the amusing or capricious ideas which always seduce you too easily. Remember that in the career you are following, intelligence is not enough and that a single imprudence may become an irreparable misfortune. And finally sometime allow prudent friendship to guide your pleasures.

Good-bye, I still love you as much as if you were reasonable. "

― Pierre Choderlos de Laclos , Les Liaisons dangereuses
