"I was born in a village in the northeast, and it wasn’t until I was quite big that I saw my first train. I climbed up and down the station bridge, quite unaware that its function was to permit people to cross from one track to another. I was convinced that the bridge had been provided to lend an exotic touch and to make the station premises a place of pleasant diversity, like some foreign playground. I remained under this delusion for quite a long time, and it was for me a very refined amusement indeed to climb up and down the bridge. I thought that it was one of the most elegant services provided by the railways. When later I discovered that the bridge was nothing more than a utilitarian device, I lost all interest in it. Again, when as a child I saw photographs of subway trains in picture books, it never occurred to me that they had been invented out of practical necessity; I could only suppose that riding underground instead of on the surface must be a novel and delightful pastime. I have been sickly ever since I was a child and have frequently been confined to bed. How often as I lay there I used to think what uninspired decorations sheets and pillow cases make. It wasn’t until I was about twenty that I realized that they actually served a practical purpose, and this revelation of human dullness stirred dark depression in me."
