in ''the metamorphosis'' how does Grete change from the beggining to the end of the story?

Grete is initially the only one in the family with whom Gregor was intimate. At first, she takes it upon herself to clean his room and feed him. With time, however, she loses interest in this and leaves him alone. Grete, who first cared so much for Gregor, is also the first to assert that the family must get rid of him.
