This was the second time I read the metamorphosis but I still don’t like it. The story is in the sphere of magic realism where a traveling salesman gets turned into a giant cockroach and his family is forced to take care of him. Apart from this first metamorphosis nothing really happens, it’s a realistic description of how life would be like without thoughts on why this happened. One explanation might be that Gregor was living like a cockroach before, anti-social and just working his life away.
Gregor lives through the goals of others and doesn’t have any life plans himself. Taking care of the family this way makes them inactive and lazy. Once the metamorphosis takes place it forces the rest of the family to get active again. The sister and father take up work whilst the mother works from home.
I spent a lot of time trying to figure out the apartment layout. This is the closest I got.
