When Gilberte, who, as a rule, gave her tea-parties on the days when her mother was "at home", had for some reason to go out, and I was therefore free to attend Mme. Swann's "kettledrum", I would find her dressed in one of her lovely gowns, some of which were of taffeta, others of grosgrain, or of velvet, or of crêpe-de-Chine, or satin or silk, gowns which, not being loose like those that she generally wore in the house but buttoned up tight as though she were just going out in them, gave to her stay-at-home laziness on those afternoons something alert and energetic.
