I am an university student. I once thought life at university is excellent, but now I changed my mind. I
have three roommates, and I was the last one move into the dormitory. Last term, we got along peaceful and
happily. But I find they are not willing to be with me now. They don't talk with me, and they 've become even
cold towards me than before. Many time, I wanted to talk with my roommates about that how I felt, but I
failed to find an opening. When leaving alone, I always recall this sadness. I am an honest student. Why can
I win true friendship?
