One of the authors themes is isolation. What details in lines 28-40 support this theme?

A detail in lines 48-20 that provides support for the theme is the fact that Gregor did not have time to socialize and therefore did not have any friends.

Explanation:

This question is about "Metamorphosis" written by Kafka, where we met Gregor Sansa, a man who wakes up transformed into a giant insect. The book questions the value of humanity in the face of its family and the demands of capitalism.

One of the themes covered in the story is isolation. This theme is reinforced by the fact that Gregor spent so much time working that he didn't have time to socialize, make friends and have people to talk to and have fun with. He lived in isolation, even though his family lived in the same house as him.
