Dear Smith,

     I'm an university student. I once thought life at the university must be excellent, but now I

changed my mind . I have three roommate, and I was the last one to move into the

dormitory. Last term, I got along peacefully and happy. But I find they are not willing to

be with me now. They don't talk with me, and they have become cold toward me. Many

time, I have wanted to talk with them about how I felt like, but I failed to find an opening.

When leaving alone, I always recall this sadness. But I am an honest student. Why don't I

win true friendship?
