Symbol of the House

In Julio Cortazar's House Taken Over, the main character and his sister Irene lives in a house left by their grandparents for years. They have a odd routine of life, Irene's routine is getting up, clean the house, then spend the rest of the day knitting supplies such as sweaters. The main character's life is getting up, clean the house, then spend the rest of the day either watch Irene knit or read French literature that has been read long ago. He goes out to buy supplies and look for French literature once in a week. This is a rather odd lifestyle, they have almost absolutely no contact with the outside world and they just live in the house, their little world. The house acts as a symbol in the story, it can be a symbol of their sanity. They've been living in their little world and at the climax of the story, their house is slowly taken over. This can mean that they are slowly going insane and they can't take it anymore. The house can also be a symbol of life, a rather boring life however. They've lived in the house since the start of the story, which is probably a very big portion of their life near the end of the story the house is slowly taken over, meaning they are slowly dying, leaving the world they never had contact with. The story is filled with symbols and because it is a magic realism so the story does not have to perfectly logical or even logical at all. This is what makes the story good. The readers have to interpret what the symbol is and there are no right answer for sure and because the story doesn't have to be logical, the choices of symbols become wider.
