"You will find in every circle that etiquette holds some sway; her rule is despotic in some places, in others mild, and easily set aside. Remember, however, “once a gentleman always a gentleman,” and be sure that you can so carry out the rule, that in your most careless, joyous moments, when freest from the restraints of etiquette, you can still be recognizable as a gentleman by every act, word, or look." Cecil Hartley - Gröls Classics - English Edition
