Dear Sir or Madam,

I am writing to inform you that I wish to move into a new room next term. I would prefer a single room, as I find the present sharing arrangement inconvenient.

The reason for my dissatisfaction is my roommate’s inconsiderate behavior. His friends constantly visit him and he regularly holds noisy parties. In addition, he sometimes borrows my things without asking me. Under these circumstances, I find it different to concentrate on my studies, and I am falling behind on my assignments.

I am sure you will agree that the solution is for me to move into a room of my own, where I will be free from such distraction. I would be grateful if you could fond a single room for me, preferably not in the same building but as near to the college campus as possible.

                                                            Yours sincerely,

                                                                 Li Ming
