I see a humor about the question of the final examination. It is a college school final examination. There is only one question that is who is the teacher of this class, and the answer is four faces. This is just a humor from Japan but it is a common problem in the world.
The college students don’t go to class and just prepare the exam from other students’ notes. He can get a pass and he can learn something although a little, but he doesn’t know the teacher of course. The world teaches us to respect our teacher, but in the college, students even don’t know the faces of the teachers. Can the respect exist? I don’t think so.
After laughing for the humor, I drop into deep thought.
