It is five years now since I graduate from No.3 High

School.Last Saturday,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 abroad for further studies,but they called back

or sent greeting card from different places.
