There were not many steps. I had counted them a thousand times, both going up and coming down, but the figure has gone from my mind. I have never known whether you should say one with your foot on the sidewalk, two with the following foot on the first step, and so on, or whether the sidewalk shouldn't count. At the top of the steps I fell foul of the same dilemma. In the other direction, I mean from top to botoom, it was the same, the word is not too strong. I did not know where to begin nor where to end, that's the truth of the matter. I arrived therefore at three totally different figures, without ever knowing which of them was right. And when I say that the figure has gone from my mind, I mean that none of the three figures is with me any more , in my mind. It is true that if I were to find, in my mind, where it is certainly to be found, one of these figures, I would find it and it alone, without being able to deduce from it the other two. And even were I to recover two, I would not know the third. No, I would have to find all three , in my mind in order to know all three. Memories are killing.
