"The wise always use a number of ready-made phrases (at the moment I write 'nobody's business' is the most common), popular adjectives (like 'divine' or 'shy-making'), verbs that you only know the meaning of if you live in the right set (like 'dunch'), which give a homely sparkle to small talk and avoid the necessity of thought. The Americans, who are the most efficient people on earth, have carried this device to such a height of perfection and have invented so wide a range of pithy and hackneyed phrases that they can carry on an amusing and animated conversation without giving a moment's reflection to what they are saying and so leave their minds free to consider the more important matters of big business and fornication."
