What interesting things happened between you and the class teacher?

I remember that my class teacher was very funny in senior three. When we are more than a month away from the college entrance examination, everyone is very nervous. The atmosphere in the classroom is always heavy every night. In order to relax us, the head teacher broke into the classroom in a huge ugly puppet suit on a hot day. As a middle-aged man in his forties, he twisted and twisted on the platform and clumsily tried to dance. First, we were made to burst into laughter, and then we threw him out of the puppet.

He still foolishly thought that we didn't know it was him, and he was so hot that he was sweating all over and tried to cover his head and wouldn't let us take it off. Moreover, during that time, it was often rumored that some students in a certain school in the county had jumped off the building. The details were said to have eyes and noses, but they were all catching shadows. The head teacher worries every day whether we will jump a few times because of the pressure of the college entrance examination. After all, our class is on the sixth floor and it is hopeless.

So every time he finished the paper, he would leave five minutes to talk to us about life and ideals. He even offered a "lure", saying that he would teach us the unique secret of getting rid of the bill quickly in college after we finished the exam. But in order to spare these five minutes, he spoke a little faster than usual, which sounded more difficult.

So when he was ready to talk about life again, we all swore: We won't jump off a building in the old class, so don't talk about life, let's talk about the topic slowly. The old class was peeped through by us, smiled wryly, and then stopped talking about life. We thought he was finally normal. Never thought! One day I came out of the classroom and saw him installing barbed wire in the corridor! In fact, what the head teacher did was funny, but we were very moved to know that he was trying to relieve our pressure.
