While we see a typical fight between brothers in a bedroom, we hear in off the father’s voice considering whether or not to use his savings, in order to build a another bedroom so that each has their own room.

While we he continues to think, he realizes that actually, sharing the room is better, even if they’re old and fight.

Finally, we discover the father in a CarOne dealership, about to buy a car, and we understand that actually the whole story was just a way for him to convince himself that it’s better to buy the car than build another room.
