Enter company shyly. Make it a habit to order the large size of anything. Never walk forth and introduce yourself or heap helpings from your host’s sideboard without being beseeched for the second time to do so. Never fear to chat with chaps who have been knocked on their arses by misfortune. Instead of befriending the mighty, be kind to little children. Demand a good price for anything you sell and never pay over the market for anything you buy. Screw other men’s wives only when they implore you to.
