Read this passage: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.
