Yes. You are correct about the real life version. I just saw a little documentary on it a few days ago. Couple boys in Tonga stole a boat and took it out. They hit a storm and were shipped wreck on a deserted island. I believe it was for 15 months. They were rescued by an Australian fisherman. A news station heard about it and had the boys reenact how they lived for the camera before they went home. Upon return home they were arrested for stealing the boat. The Australian fisherman paid off the boat and the boys were released. 1 became a priest and 1 became best friends and worked for the fisherman. Kind of funny hearing how they resolved differences. Sometimes they argued. Sometimes they had fist fights. But after cooling off they always came back together. ....sorry for droning on. But that's the story.
