You, are Mark or Sally, and live in a room in college which you share with another student. You find it very difficult to work there because your roommate always has friends visiting. He/She has parties in the room and sometimes borrows your things without asking you. Write to the Accommodation Officer at the college:
1)asking for a new room next term 2) stating that you would prefer a single room, and 3）explaining your reasons.
Dear Sir or Madam, I do not wish to sound overcritical but, I am finding it increasingly difficult to get on with my roommate. I take my studies seriously which seems to be the opposite for her. She is continually inviting her friends to our room which makes it impossible for me to do the necessary study. In addition, she borrows my things without asking. I would greatly appreciate it if you could allocate me a different room next semester, preferably in the same building but on a different floor if one is available. Thanking you for your consideration.
