Hello! I would say the narrator is insane because he can still hear the old man’s heart thumping from underneath the floorboards even after he killed him. His guilt gets the better of him and he turns himself in to the cops. I don’t have any evidence sense I don’t have the story on me, but use something from the story along the lines where he “hears” the thumping of his heart as evidence.
Answer:
Provide for the common defence
The Outsiders are about a journal entry that the main character Ponyboy is writing for his English Homework. He is part of the group called the Greasers. Another group are the Socs and they are enemies. One day Ponyboy and his friend Johnny find themselves in trouble with the Socs. While they are fighting, Johnny takes out his knife and stabs Bob, fatally killing him. They run away to an abandoned church, where they stay a couple of days. Soon, Dally picks them up and they see that the church is up in flames and some kids are trapped in there. They go rescue them but a giant piece of wood falls on Johnny and is sent to the hospital. The rest of the gang is there and Johnny is charged for killing Bob. Because of the Socs and the Greasers have a fight. The Greasers win. Unfortunately, Johnny dies in the hospital and Dally robs a store because of this. As he is running with the merchandise, he is hot by the police. The story ends just how it started as Ponyboy is writing his journal entry about these vents.
