He would often lie there the whole night through, not sleeping a wink but scratching at the leather for hours on end. Or he might go to all the effort of pushing a chair to the window, climbing up onto the sill and, propped up in the chair, leaning on the window to stare out of it. He had used to feel a great sense of freedom from doing this, but doing it now was obviously something more remembered than experienced, as what he actually saw in this way was becoming less distinct every day, even things that were quite near; he had used to curse the ever-present view of the hospital across the street, but now he could not see it at all, and if he had not known that he lived in Charlottenstrasse, which was a quiet street despite being in the middle of the city, he could have thought that he was looking out the window at a barren waste where the grey sky and the grey earth mingled inseparably. His observant sister only needed to notice the chair twice before she would always push it back to its exact position by the window after she had tidied up the room, and even left the inner pane of the window open from then on. If Gregor had only been able to speak to his sister and thank her for all that she had to do for him it would have been easier for him to bear it; but as it was it caused him pain. His sister, naturally, tried as far as possible to pretend there was nothing burdensome about it, and the longer it went on, of course, the better she was able to do so, but as time went by Gregor was also able to see through it all so much better. It had even become very unpleasant for him, now, whenever she entered the room. No sooner had she come in than she would quickly close the door as a precaution so that no-one would have to suffer the view into Gregor’s room, then she would go straight to the window and pull it hurriedly open almost as if she were suffocating. Even if it was cold, she would stay at the window breathing deeply for a little while. She would alarm Gregor twice a day with this running about and noise making; he would stay under the couch shivering the whole while, knowing full well that she would certainly have liked to spare him this ordeal, but it was impossible for her to be in the same room with him with the windows closed.
