Why did father narrate the 2 stories in bringing tony home

Father may have been using the two stories to explain to Tony the consequences of his actions. He wanted to point out the importance of responsibility and the consequences of taking action without thinking about the long-term effects. By illustrating how his own actions had come back to haunt him, father could show Tony that he must consider the consequences of his actions in the future if he wants to be successful. Father may also have been hoping that his story could serve as a lesson that Tony could learn from and apply in his own life.
