I read a book, 'The Red Badge of Courage'. The main character is a boy. He wanted to be a hero and fight for his country and its people. Therefor he decided to leave home and join the army. He also had to get permission from his mother. However his mother cried about this. She didn't want him to get hurt. She needed him here on the farm more than the army needed him. But he left his home and join the army. At first, he was happy because he could join the army and become a hero. Gragually he wanted to go home and felt fear.
