your world my tomorrow

In physics class on Thursday afternoon, a new intern male teacher, Chen Da, looked a little green, and looked nervously at his classmates with a pair of black-rimmed glasses.

This is his last chance. He has failed several times in a row in the graduation internship teaching class. If he fails this time, he will really not be able to get his graduation certificate!

Chen Da looked at the invigilator in the row behind, and he talked about the conditions of friction force hesitantly. After he finished speaking, he cleared his throat specially, and told a joke that he had prepared for a long time:

"Students! In fact, there are also physical phenomena in the four famous Chinese books. For example, in "Journey to the West", Tang Seng crossed the Tongtian River. Why did he tie grass and cloth? This is physics, which increases friction so that it can move on smooth ice. Walk on the face, otherwise Tang Seng will all fall to death, and then there will be no follow-up to learn the truth, the author can only write: The story ends here, Tang Seng and his group fell to death, hahaha... oh~~heh~~ , no, isn't it funny?"

Seeing that none of the students reacted, Chen Da wiped the sweat from his forehead, looked at the roster and wanted to ask some students to share the examples of friction around them.

"That...Qi, student Qi Shun, please stand up and tell everyone what other examples of friction force around us, student Qi? Who is student Qi? Is he not here?"

"That... teacher, he, he is sleeping, you can call someone else." The students in the front row kindly reminded.

"Student Qi, wake up, don't fall asleep in class, you wake him up." Chen Da didn't even know that in this school, Qi Shun's coming to class was just a decoration, and he could be ignored at all.

No one dared to call, and Fei Qinan didn't want to be troublesome at all. Everyone looked at each other in blank dismay. The row of teachers in the back certainly knew this, so it was hard to stop them.

Chen Da came to Qi Shun with the book and patted him on the back.

"Student, classmate, wake up~~wake up~~don't sleep~!"

Qi Shun finally woke up, wiped the drool on his face, and looked up at Chen Da beside him.

"what?"

"Student Qi, school is not a place for you to sleep. I just asked you to give a few examples of the application of friction in life by name."

"Friction force?" Qi Shun was stunned, it was the first time he was woken up to answer a question while sleeping, this teacher came from an alien, right?

"Yes, friction! Do you know what kind of friction exists in our life?" Chen Da advised himself to be calm, to be calm.

Qi Shun looked around, and focused on the back of the front of his head, seeing this situation, he immediately became interested.He lazily got up, and Chen Da was suddenly a head shorter than him.

"Same, classmate, what are you going to do?" Seeing that his image was too different from other students, Chen Da was a little scared.

"Teacher, didn't you ask me to answer the question? Of course I have to stand up." Qi Shun smiled wickedly.

"Then, tell me about it."

"Friction, right? Let me think about it....Is it the result of friction to wipe the blackboard?" Qi Shun tilted his head and thought for a while.

"Yes! What else?"

"And the speed bumps of the cars on the road...isn't it?"

"Yes, is there any more?"

"Also... our great human reproduction is also thanks to the friction force... right teacher?" Qi Shun looked at Chen Da with a smile on purpose after speaking.

The people in the classroom immediately understood the meaning, burst into laughter, and the face of the teacher in the back row turned red and white.

Qi Shun proudly looked at his masterpiece of disrupting the classroom, but when he saw Fei Qinan's back that didn't care at all, he suppressed his smile.

"Same, classmate, please sit down, let's continue, continue with the class." At this moment, Chen Da's mind went blank, and he didn't know how he finished the rest of the class.

After class, he looked at Qi Shun angrily, and when he got back, he would draw circles and curse that dishonest student.

After the friction force passed, Qi Shun didn't feel sleepy anymore. He flipped through the brand new book in every possible way, and patted Fei Qinan on the shoulder as if he suddenly thought of something:

"Hey~~student, how about I take you to skip class to play something exciting?"

Fei Qinan shook his head and refused, Qi Shun patted again and asked:

"Then why don't we go to the bathroom together? By the way, let's discuss the issue of friction?"

"Go by yourself, I'm not interested."

"Then what are you interested in?" Qi Shun thought this guy was really rude.

"I'm interested in everything you're not interested in."

"Oh? Really? There's one thing you're sure won't be interested in."

"what?"

"I'm not interested in myself, are you interested in me?"
