When I was a high school student, I violated my school's rules. I was a senior high school and it was time to near the national colleage extrance exam. So teachers didn't educate their students and we studied ourselves in the classroom. At that time, I wanted to go to my own study room and study alone. Because there are students who didn't study and hanged out with their friends. It was so noisy in the classroom. So I lied to my teacher that I am so hurt and I went to my own study room. It was good for me but I felt guilty because I lied for my teacher. So I didn't do that again.
