Dear Sir or Madam,
I am writing to inform you that I wish to move into a new room next semester. As I find the present sharing arrangement inconvenient, I would prefer a single room.
The reason for my complaint is my roommate's behavior. His friends visit him constantly and he regularly holds noisy parties. In these circumstances, I find it difficult to concentrate on my studies, and I am falling behind in my class.
I think that the only solution for me is to move into a room of my own. I would be grateful if you could find a single room for me, preferably not in the same building but as near to the college campus as possible.Yours sincerely,
Li Ming
