Dear David,
I am an university student. I once thought life at the university must be excellent, but now I changed my mind. I have three roommates, and I was the last one 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’ve become cold towards me. Many time, I 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?
