13. No gentleman will ever criticize a wine offered to him, no matter how poor it may be. We give an instance of undaunted etiquette, which proves to what an extent a well-bred man may carry his courtesy: "In England during the French Revolution, the Duke of Bedford invited the emigrant Duc de Grammont to a splendid dinner, one of those magnificent entertainments which Englishmen pride themselves on giving to crowned heads, and their good feeling prompts them to offer to exiles. During dessert, a bottle of Constantia was produced, which for age and flavor was supposed to be matchless. It was liquid gold in a crystal flagon--a ray of the sun descending into a goblet; it was nectar which was worthy of Jove, and in which Bacchus would have revelled. The noble head of the house of Russell himself helped his guest to a glass of this choice wine, and de Grammont, on tasting it, declared it to be excellent. The Duke of Bedford, anxious to judge of its quality, poured out a glass, which no sooner approached his lips than, with a horrible contortion, he exclaimed: 'Why, what on earth is this?' The butler approached, took the bottle and applied it to his nostrils, and, to the dismay of his master, pronounced it to be castor-oil. The Duc de Grammont had swallowed this horrid draught without wincing." 14. Flattery is a breach of etiquette. Johnson says: "Of all wild beasts, preserve me from a tyrant; and of all tame, a flatterer." 15. No gentleman may ever break an engagement, whether it be one of business or pleasure, with a lady, or with another gentleman. If not blessed with a retentive memory, he must carry a note-book and record therein all his appointments, guarding, by frequent reference, against making two for the same day and hour. To break an engagement with a lady is almost certain to give lasting offence, and with good cause. 16. Irritability is a breach of good manners. Watts says: "To be angry about trifles is mean and childish; to rage and be furious is brutish, and to maintain perpetual wrath is akin to the practice and temper of fiends; but to prevent and suppress rising resentment is wise and glorious, is manly and divine." 17. Nothing marks a gentleman more truly than a strict punctuality. To keep another waiting is a breach of etiquette, as well as often a positive unkindness.
