The year I was promoted from the second grade to the third grade, because I was quite naughty and my parents were really helpless, they sent me to a private school over there. They dressed me up so well that day that the principal of that school praised me for being well-behaved, although I knew it was just a polite comment. The high wall separated me from the outside world. The hustle and bustle outside belongs to others, and I own nothing. The happiest thing every day is to go to the lawn with the boys to catch crickets in mineral water bottles and play during evening self-study.

I was sitting in the front row, and Cricket was overwhelmed by my torture and decided to escape from prison. I ran to the podium. I don’t know if it was because of the demons that I tortured, but it actually jumped into our physics teacher’s cup. After the middle-aged man picked up the cup and looked at it for a while to make sure that it was not something poisonous, Drink it. This was the first time in my life that I saw someone drinking crickets, which really shocked me.

If it were just this one thing, and I remembered it for a few days, I would probably forget it after a while. When reviewing the electrostatic reaction in the first class, he took out a comb from his pocket and rubbed it on his hair for a while, just like a magic trick. Then he got some scraps of paper and used the static electricity on the comb to absorb them. A little paper scraps, maybe he thought the static electricity reaction was not obvious enough, so he took off his shoes again, then took out the insole and wiped it on the comb twice. The electrostatic reaction was more obvious now, and a lot of paper scraps on the table were sucked up. This class was spent rubbing the comb. When get out of class was over, he picked up the comb he had rubbed with his insole and combed his hair.

This is not the cutest thing about him. The cutest thing about him is that when he comes to class, he wears his pants inside out. Our squad leader has sharp eyes and can tell at a glance. After telling us secretly, we laughed for a long time. Although I tried my best not to laugh, I couldn't hold it in when I saw his pants. The class monitor reminded him kindly. As expected of an old man in his forties, he stood on the podium without any fear and said righteously: "It's just that your pants are on backwards. You guys are so funny that you laughed for the whole class."

It was such a slovenly middle-aged man who used his unique and funny way to lead me into the magical world of physics, which made me interested in this subject. It is also because he made our boring life in the third grade of junior high school very happy. It is also his subtle influence that imparts to us a positive world view and attitude towards life. Even seven years after I graduated from junior high school, when I think of him again, the corners of my mouth can't help but curl up, and my heart is filled with gratitude.
