It was on a warm autumn day that my father and I walk into my new high school. After registered in the classroom, the volunteer took me to my dormitory. Altogether I had five roommates, two of which arrived later. I got to know my new roommate immediately. Although I was quite unwilling to say “Goodbye” to my father, but he had to leave to my hometown in the evening. I suddenly realized I had grown up and that I had to look after me and live independently. Not until then I know my senior high school life had real begun.
