It is three years now since I graduate from No. 1 High School. Last Sunday, the class that I was on held a get-together, which took us a long time prepare. It was indeed not easy to get in the touch with everybody and set a well time for all of us. We all enjoyed this precious day greatly, remember the time we spent together and the people they were familiar with. It was a pity which some of us were not present as they had gone to abroad for further studies, but they called back or sent greeting card from different places.
