The next morning, the two of them go for a walk, and the dog tells the boy that he's not the only one who's mad at him. He's the one who didn't agree with him on the whole thing, and he still doesn't want to admit it. The dog tells him to calm down, and then he'll tell him what happened the night before. He asks the boy if he remembers something important that happened that day. The boy tells him that he forgot something important, and asks the dog to remind him of it, so that he won't be able to repeat it later. He tells the dog that he understands why his brother treats him differently now, and that's because his uncle controls him. When the dog asks why, the boy explains that his brother asked his uncle for money four years ago, but his uncle wouldn't let him enter the competition because he was still in school. So, when the boy returned, he signed a deal with a small company to get the money. This is why the dog is mad, because he wants his uncle to treat his brother well.
