Once Bruno falls off of his homemade tyre swing, he is hurt and has cuts and scrapes. Bruno keeps asking if he needs to be taken to the hospital, or if he was going to bleed to death. This tells us that Bruno can be dramatic, but it has now exposed him to understanding the other people in the house besides his family. For example, Pavel helped Bruno when he fell of the swing, and Bruno discovered that Pavel used to be a doctor, before he did housework for the family.
