The moment when I finished my college entrance exam, I felt so excited, it seemed that the biggest task of my life has been done. The whole night, my classmates and I went to KTV and celebrated the future of our life. When I started to realize that it was time to say goodbye to my classmates and teachers, I felt sad. My classmates and I studied and made progress together. We fought for our future for three years, and the relationship between us were like brothers and sisters. What' more, the teachers took care of us all the time, and they passed us the knowledge and educated us to explore the world. All of them had been part of my life. It was so hard to say goodbye to them. So we made a deal, every ten years, we would go back to school and get-together.
