    When I was a teenager growing up in Russia, I wanted to leave school and have my own life. The only way I could do this was to work in the local brick factory in my town, or get married. I was nervous when I told my father I wanted to leave school. I thought he would say, "No! You are going to college." He took me by surprise when he said, “OK. We'll go to the brick factory.”
    Two days later, he took me to the factory. I had a very romantic idea of working in a factory. I had imagined everyone to be friends working together and having fun. I even imagined there would be music and singing. I guess I had watched too many movies as a teenager.
    When we arrived at the factory gate, my father spoke to the guard and one minute later we were inside. My father said, “Take your time. Look around.” I walked around the factory looking at the building, the workers, and listening to the noise. It was horrible. I ran back to my father and said, “I want to go home.”
    He asked me, “What do you think of the factory?”
    "It's terrible," I replied.
    "And marriage is even worse!" he said.
    I went back to school the next day thinking about studying hard so I could get into a good college. I enjoyed studying English so I decided to major in languages at college. Thanks to my father and our trip to the brick factory, I now work at the United Nations and my father is very proud of me. I married a very good man and my life is much better than it would have been working in the factory!
