changes in gretes life ?

Every night Grete and her mother struggle to get the father into bed, and then they sit together until it's time to close the door of Gregor's room.

In Chapter Three, Grete doesn't bother to pick out Gregor's food any more and cleans his room very hastily and poorly. She insists, however, in being the only one to clean his room and, when his mother does this once, Grete yells at her starting a fight with the father who reprimands them both.

After taking on the lodgers notice Gregor and stare at him with amusement. It's at this point that she steps forward and forcefully tells her parents that they have looked after the creature long enough and must now get rid of it. She bursts out crying. The father asks how they could get rid of it, and Grete has no answer. She ridicules the idea that Gregor can understand them and insists that, if this were really Gregor, he would have gone away on his own and left them alone. She claims that the creature is persecuting them and wants to drive them out of the apartment into the gutter.

When Gregor attempts to turn around, Grete panics. Finally, he manages to crawl back painfully to his room and his sister slams the door shut behind him and locks it. Gregor, remembering his tenderness and love for his family, realizes that he has to disappear. He agrees fully with his sister. He dies as the dawn is rising.
