6th grade teacher's father

During my sixth grade year I attended a club that was led by one of my favorite teachers. He loved to tell stories, especially about him and his father. He told us stories of how his father joined the army and what happened to him as told by his father. Because I could not get a hold of him this story is solely based on my memory.
My teacher’s father had just finished college when he began to think of what he was going to do with the rest of his life. He had graduated with an English degree and he didn't know how he was going to be able to put it to practice. Even though he did not have a plan, returning back home was not really something he wanted to do. He had a tense relationship with his father because his father did not approve of his decision to focus on English. One of his friends had enlisted to the air force, while his closest friend had enlisted in the army. He really enjoyed the idea of becoming a pilot and roaming the world while defending his country. However, he soon discovered he had problems with his depth perception. Because of this he was not aloud to enlist in the air force. Searching for any that aloud him to avoid home he decided to join his best friend in the army. My teacher believes that his father joined the army because of all of the hype going on about fulfilling his duty for his country and also because of peer pressure from his friends. But in reality we don’t know.
