The keynote of American civilization is a sort of warm-hearted vulgarity. The Americans have none of the irony of the English, none of their cool poise, none of their manner. But they do have friendliness. Where an Englishman would give you his card, an American would very likely give you his shirt.
Americans are very friendly and very suspicious, that is what Americans are and that is what always upsets the foreigner, who deals with them, they are so friendly how can they be so suspicious they are so suspicious how can they be so friendly but they just are.
