The Metamorphosis is constructed in three acts, each involving an escape by Gregor from his room and a return to it. With each retreat, Gregor becomes noticeably less human and more accepting of his transformative state. With each act, Gregor also becomes physically weaker. As his family abandons its denial of his insectlike appearance and their hope for his full recovery to a normal human condition, they gradually become indifferent to his fate and recognize their need to pursue their lives without him.
