READ: I am Sam Sue, I am twenty-four years old, and I am from Spain. I live in a small house in Barcelona with my best friend, Lenn, and I am a receptionist. I work in a big hotel here and I wear a yellow and white uniform. I have a lory and I drive to the hotel every morning. I drink a lot of tea because I work long hours, but I like my job because I meet people from different countries.
My parents have a house in a town. I have two brothers. Their names are Jan and Wen. Jan is a student and Wen is a chef in a restaurant . My father works but my mother is retired now.
I do not do a lot of sport, but I sometimes play tavla with Lenn. I love music. My favourite kind of music is Spain opera and I listen to it in my car and on my iPod. I also play the guitar and the piano. On Thursdays I study English at a language school because I want to work in London. At weekends, I visit my family or I stay here and go to the cinema with my friends.
