Number of changes began from the first day of middle school. My life became more colourful and interesting than ever before. I faced a lot and learned a lot. but now all I can feel is how time flies. in the past three years, we were together: we worked hard on studying; we laughed from the deep of our hearts; we get through all the difficult periods. Now it is time to leave. it is too reluctant to say goodbye to those days, classmates and teachers. How time flies!
