What theme does the following excerpt from franz kafka's the metamorphosis deal with?

this was how gregor received his food each day now, once in the morning while his parents and the maid were still asleep, and the second time after everyone had eaten their meal at midday as his parents would sleep for a little while then as well, and gregor's sister would send the maid away on some errand. gregor's father and mother certainly did not want him to starve either, but perhaps it would have been more than they could stand to have any more experience of his feeding than being told about it, and perhaps his sister wanted to spare them what distress she could as they were indeed suffering enough

The theme of a close familial bond, closeness between family members.

Explanation:

The short story "The Metamorphosis" by Franz Kafka tells the story of one travelling salesman, Gregor's transformation into an insect one day. It tells the story of how his family dealt with this change.

The given excerpt in the question deals with the theme of the close bond of the family members. Though appearing different and maybe even disgusting, Gregor's sister made sure he's eating and that too, regularly. She made sure that he is provided food, even thinking about their parents' comfort, "his sister wanted to spare them what distress she could as they were indeed suffering enough". The passage also mentions that his "father and mother certainly did not want him to starve either", which shows how they still do care about their son even if he's now a different being.
