But what is the sense in forever speculating what might have happened had such and such a moment turned out differently? One could presumably drive oneself to distraction in this way. In any case, while it is all very well to talk of 'turning points', one can surely only recognize such moments in retrospect. Naturally, when one looks back to such instances today, they may indeed take the appearance of being crucial, precious moments in one's life; but of course, at the time, this was not the impression one had. Rather, it was as though one had available a never-ending number of days, months, years in which to sort out the vagaries of one's relationship with Miss Kenton; an infinite number of further opportunities in which to remedy the effect of this or that misunderstanding. There was surely nothing to indicate at the time that such evidently small incidents would render whole dreams forever irredeemable.
