Last week, a friend of mine came to visit me, I felt so surprised, because we lose touch for many years, he was my classmate when I was in primary school, now five years has passed, both of us have entered college. My friend told me that he was doing a research, he remembered my home address, so he came to visit me. We talked many things in primary school, it was a beautiful memory, both of us were naughty at that time, but we loved sport, we played the basketball match and won the first place. When the time he left, we made the deal to be gather for the next time.
