In Metamorphoses, by Franz Kafka Gregor Samsa is outnumbered and overpowered by the forces surrounding him. He starts off in a family friendly environment. He has two parents whom he supports by working hard and he has a sister whom he deeply cares about and she reciprocates those feelings. Gregor works for the sole purpose of providing for his family because they are incapable of taking care of themselves. He undergoes huge changes one night and his family goes from respecting him to fearing and lamenting the new person he has become. Gregor is mistreated by his family and even his beloved sister begins to show hate and regret and that is when Gregor becomes a by-product of his environment. He becomes depressed and uncomfortable, he feels abandoned so he unintentionally starts to cause trouble. The family invites borders to live with them and pay rent in order to maintain their fiancés, but instead of staying out of sight Gregor is attracted to the music his sister produces and reveals himself. He is physically hurt by his father and shunned by his sister.
The stress his family bestowed upon him from the beginning and their poor sense of sensitivity and understanding forces Gregor to feel isolated. His one priority was providing for his family and sending his sister to further her education and the very things he worked for have turned on him. He chooses not to eat and becomes malnourished, this suggest how bad it is for Gregor living in his house. The interior world that Gregor held so dearly was destroyed by his family which in hindsight was his environment.
