Graduation finally came. My classmates and I made up our mind do something. Someone suggested make a video to record our experiences at school and we agreed. Material collecting took us a whole week, during it we interviewed our teachers and took picture of every aspect of school life. The editing part after that was tough. We debated over what to put them into the video. Some disagreements were unavoidable, and the video turned out perfect. Several days later, when the video was played on a graduation ceremony, it was very popular for everyone. What a wonderfully time the students and teachers shared! That surely gives us a great sense of achievement.
