Dear Smith，

I’m an university student. I once think life at the university must be excellent, and now I have changed my mind . I had three roommate, and I was the last one to move in the dormitory. Last term, I got along peacefully and happy. But I find they are willing to be with me now. They don’t talk with me, and they have become colder towards me than ago. Many times, I wanted to talk with them about how I felt, but I failed to find an opening. I have been feeling sad and lonely. Although I am an honest student, but I can’t win true friendship.

Yours sincerely,

Tom
