I half closed my eyes and imagined this was the spot where everything I'd ever lost since my childhood had washed up, and I was now standing here in front of it, and if I waited long enough, a tiny figure would appear on the horizon across the field and gradually get larger until I'd see it was Tommy, and he'd wave, and maybe even call.

That was the only time, as I stood there, looking at that strange rubbish, feeling the wind coming across those empty fields, that I started to imagine just a little fantasy thing, because this was Norfolk after all, and it was only a couple of weeks since I’d lost him. I was thinking about the rubbish, the flapping plastic in the branches, the shore-line of odd stuff caught along the fencing, and I half-closed my eyes and imagined this was the spot where everything I'd ever lost since my childhood had washed up, and I was now standing here in front of it, and if I waited long enough, a tiny figure would appear on the horizon across the field, and gradually get larger until I'd see it was Tommy, and he'd wave, maybe even call. The fantasy never got beyond that --I didn't let it-- and though the tears rolled down my face, I wasn't sobbing or out of control. I just waited a bit, then turned back to the car, to drive off to wherever it was I was supposed to be.

What I'm not sure about, is if our lives have been so different from the lives of the people we save. We all complete. Maybe none of us really understand what we've lived through, or feel we've had enough time.

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.
