Kafka's "The Metamorphosis" is a short story about Gregor, a traveling salesman who wakes up as an insect one day. The story is told from a 3rd person point of view from the time he wakes up as an insect until his death.

We learn in the beginning of the story that Gregor is the breadwinner of the family before he turns into an insect. He makes money to pay for the apartment, put food on the table, and pay off his parents debt. He parents are "unable" to work; however, after Gregor becomes an insect, his father finds a job quickly, so he may have been lazily mooching off of his son the whole time. The family is also very unappreciative of what Gregor does for them; they never thank him.

Even after all he's done for the family, he is viewed as a burden shortly after turning into an insect. The family feeds him scraps from their dinner and keep him in his room. When Gregor comes out, the people renting a room family the family see him and they leave immediately. Gregor is aware that he is causing problems for the family, so he sacrifices himself for their well being and dies.

After Gregor's death, the family doesn't take time to mourn, they simply move to another apartment and forget about him. Gregor has cared about and provided for the family, and the family just takes Gregor for granted.
