Dear Sir/Madam, I am writing to express my dissatisfaction with my roommate. As you know we share one place, I can not study in the place at all any more if I still stay there. She always has friends visiting and having parties in the place. They make lots of noise and switch on the radio very loudly, for ,me this environment is very difficult to study and I need a quiet place. Even borrows my things without asking, it is very impolite. I request you can give me a new room next term because I have asked her has parties in other places many times they still have parties in the room. I really can not stay in the same room with her. I would be grateful if you could change me a single room. Your faithfully, Catherine
