Especially since I was a child, I have been a good student who studies hard and is obedient and sensible, so the teachers are naturally impressed by me.

He came in and sat for a while, chatting with us for a while. Then maybe he felt bored or out of habit, so he took out a cigarette and lit it up.

So when the teacher smoked and made the classroom full of smoke, I told him seriously about the dangers of smoking and the dangers of second-hand smoke to us. He probably felt that he was losing face, so he left without saying anything. . Later, I actually felt that I had gone too far in saying that. I thought about going to him to apologize, but I didn't go because of my face. It's been a long time since this happened, but it's still funny when I think about it now.
