Watching South Korean filibuster, I have been remembered of the teacher of my high school.
On the final semester exam, He was the supervisor of my class.
He said to us that the students who finished the exam had to put their head down on their desk.
That was his the way to prevent cheating.
Since I didn’t agree with the way, I said him why I had to do it, even though I didn’t want to cheat.
Then he got anger with me. And he said to me, “that’s why you are my student and I am your teacher.”
