Hole in my Life 3

I don't understand why Jack risked getting in trouble by writing in books. Jack could have gotten caught writing in books and received more time. He was risking a lot by writing in the books. Jack thought when he got out he would just be able to take the book with him. Well, he was wrong. The book was prison property and had to remain in the prison. If the guard just opened up the book Jack would have gotten in trouble. In prison all Jack did was write about everything that was going on. He didn't think that he had to leave the book in prison when he left. He wrote about people in the prison and if they found out it was him, then he could get in a lot of trouble. Jack realized that if he can write about prison, then he could write about the real world. The book Jack wrote in could have changed his life if the gaurd saw it. I really don't understand why Jack Gantos risked getting in trouble, just to write storys in a book. This was prison property so Jack was breaking rules. I really didn't understand this decision.
