For in this way Swann was kept in the state of painful agitation which had once before been effective in making his interest blossom into love, on the night when he had failed to find Odette at the Verdurins' and had haunted for her all evening. And he did not have (as I had, afterward, at Combray in my childhood) happy days in which to forget the sufferings that would return with the night. For his days, Swann must pass them without Odette; and as he told himself, now and then, to allow so pretty a woman to go out by herself in Paris was just as rash as to leave a case filled with jewels in the middle of the street. In this mood he would scowl furiously at the passers-by, as though they were so many pick-pockets. But their faces - a collective and formless mass - escaped the grasp of his imagination, and so failed to feed the flame of his jealousy.
