Feeling that a collision between them and us was now inevitable, and that Elstir would be certain to call me, I turned my back, like a bather preparing to meet the shock of a wave; I stopped dead and, leaving my eminent companion to pursue his way, remained where I was, stooping, as if I had suddenly become engrossed in it, towards the window of the curiosity shop which we happened to be passing at the moment, I was not sorry to give the appearance of being able to think of something other than these girls, and I was already dimly aware that when Elstir did call me up to introduce me to them I should wear that sort of challenging expression which betokens not surprise but the wish to appear as though one were surprised—so far is every one of us a bad actor, or everyone else a good thought-reader;—that I should even go so far as to point a finger to my breast, as who should ask "It is me, really, that you want?" and then run to join him, my head lowered in compliance and docility and my face coldly masking my annoyance at being torn from the study of old pottery in order to be introduced to people whom I had no wish to know.
