As for Mme. Cottard, my father was astonished that Mme. Swann could find anything to be gained by getting so utterly undistinguished a woman to come to her house, and said: "In spite of the Professor's position, I must say that I cannot understand it." Mamma, on the other hand, understood quite well; she knew that a great deal of the pleasure which a woman finds in entering a class of society different from that in which she has previously lived would be lacking if she had no means of keeping her old associates informed of those others, relatively more brilliant, with whom she has replaced them.
