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 the earth, have carried this device to such perfection and have invented so wide a range of pithy and hackneyed phrases that they can carry on 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.
