Summarize the narrator's first conversation with Bruno after he becomes a mouse.

The boy (as a mouse) stays silent until all the witches have gone. Then, he calls out for Bruno; he is surprised to hear that his voice sounds exactly the same as when he was a boy. He thinks to himself that it is not so bad being a mouse, especially because many of the bad things about being a human such as exams and wars don't happen to mice. He wanders around the floor until he finds Bruno in the audience eating a piece of bread.

The boy tries to make a plan with Bruno, who is surprised to realize that he is a mouse; he had been so focused on food that he hadn't even noticed his transformation. Bruno is quite upset at the thought of being a mouse, since he thinks it will prevent him from eating leftovers from his fridge at night. He also thinks that his parents won't like him being a mouse. The boy promises that his grandmother will understand what happened to them and makes a plan for them to get up to his grandmother's room to work things out further. He tells Bruno that they will go out into the corridor and run close to the wall all the way to his grandmother's.
