The old saying "No pain, no gain” is really right I think. That saying is true not only for the achievements we have got, but for the friendship. When I was a student of Grade 9, I had many good friends. I was very happy during that time. Because these friends could understand my thoughts and behaviors. But when we were graduated, we had to stay at different schools. Especially for me, studying at this good senior high school, often feel bored and lonely when I have a free time. Maybe when we want to need something good, we must pay something important. It is sad that I have paid my best friends!
