Read Sue’s email to her new friend and tick () A, B, or C.
Hi Carmen
I’m Sue Manners, I’m twenty-six years old, and I’m from Wales. I live in a small house in Cardiff with my best friend, Ann, and I’m a receptionist. I work in a big hotel in the centre of Cardiff and I wear a blue and white uniform. I have a car and I drive to the hotel every morning. I drink a lot of coffee because I work long hours, but I like my job because I meet people from different parts of the world.
What else do you want to know about me? Well, my parents have a house in Bangor, on the north coast of Wales. I have two sisters – their names are Jane and Wendy. Jane is a student in London and Wendy is a chef in an Italian restaurant in Bangor. My parents are retired now.
What do I do in my free time? Well, I don’t do a lot of sport, but I sometimes play tennis with Ann. I love music – my favourite kind of music is Italian 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 Spanish at a language school because I want to work in Spain. At the weekend, I visit my family or I stay in Cardiff and go to the cinema with my friends.
Write and tell me about yourself.
Sue
