I looked at my photo album the day before and it recalled my memory. When I was in primary six, I was chosen to represent the whole form to say a farewell. We all missed our college so much. On that last day of the year , our hearts sanked as we had to leave the college. After the graduation ceremony, I and my classmates sat under a big tree. We all felt depressed and had nothing to do but chatting. We really admired our principal and teachers so much. Sadness welled form our heart and some of our classmates began to wail. Time passed like an arrow, we are all adolescents now. We returned to our primary school but some of the teachers have already retired. When we reminded their mellow smile, we all missed them so much!
