The simple and elementary gestures used by a man of the world when he courteously holds out his hand to the unknown youth who is being introduced to him, and when he bows discreetly before the Ambassador to whom he is being introduced, had gradually pervaded, without his being conscious of it, the whole of Swann's social deportment, so that in the company of people of a lower grade than his own, such as the Verdurins and their friends, he instinctively shewed an assiduity, and made overtures with which, by their account, any of their 'bores' would have dispensed. He chilled, though for a moment only, on meeting Dr. Cottard; for seeing him close one eye with an ambiguous smile, before they had yet spoken to one another (a grimace which Cottard styled "letting 'em all come"), Swann supposed that the Doctor recognised him from having met him already somewhere, probably in some house of 'ill-fame,' though these he himself very rarely visited, never having made a habit of indulging in the mercenary sort of love.
