midday
before
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 . One day , about a month after Gregor 's transformation when his sister no longer had any particular reason to be shocked at his appearance , she came into the room a little earlier than usual and found him still staring out the window , motionless , and just where he would be most horrible . In itself , his sister 's not coming into the room would have been no surprise for Gregor as it would have been difficult for her to immediately open the window while he was still there , but not only did she not come in , she went straight back and closed the door behind her , a stranger would have thought he had threatened her and tried to bite her . Gregor went straight to hide himself under the couch , of course , but he had to wait until midday before his sister came back and she seemed much more uneasy than usual . It made him realise that she still found his appearance unbearable and would continue to do so , she probably even had to overcome the urge to flee when she saw the little bit of him that protruded from under the couch . One day , in order to spare her even this sight , he spent four hours carrying the bedsheet over to the couch on his back and arranged it so that he was completely covered and his sister would not be able to see him even if she bent down . If she did not think this sheet was necessary then all she had to do was take it off again , as it was clear enough that it was no pleasure for Gregor to cut himself off so completely .
