The love of functions and derivatives

Solid Geometry: ? ? ? ? ? ? ? ? !

Is this an official announcement in disguise?

This is the brilliance of the function. The function does not express the relationship between itself and the derivative, but from the perspective of solid geometry, it is denying the previous statement.Looking at the solid geometry with a dubious expression, Function sat on the handle of the derivative chair and raised his eyebrows provocatively at the solid geometry.

Solid Geometry: ...Fuck, die.

Stereo Geometry rolled her gorgeous eyes, and she had long thrown the coquettish tone that she deliberately fabricated before, and Stereo Geometry said perfunctorily in a thick voice, "You two play slowly, Zhu 99."

The door was closed with a "snap", and there was a deafening sound.

Almost at the same time as the door closed, Function jumped off the handle of the chair and retracted his left hand that was on the derivative's hand. Function still had a youthful smile on his face, except for his heart beating a little faster. ——It should be because the office is too stuffy.

The warmth in his hands disappeared in an instant.The derivative doesn't talk, it just looks at the function.

Function avoids the derivative's gaze, pretends to be heartless and changes the subject, "I did you a big favor this time, remember to treat me to dinner when you have time in the future." After all, no one can say for sure.

But the derivative didn't answer right away.

The function looks at the derivative with an inquiring gaze, just in time for the line of sight of the upper derivative.

Here we go again, that damned stare.

The function once again pretends to admire the flowers and plants planted by the derivative in the office very spinelessly.After all, I was at a loss this time. I clearly said that I needed a clear explanation of the derivative, but then I helped the derivative perform a play in front of the three-dimensional geometry like a ghost.

Wait, maybe... am I really acting?

The function has not had time to delve into the answer in it, only to hear the derivative say: "OK."

The function is relieved.

It was already getting late because of the incident of solid geometry, and Derivative offered to send Function home. Function wished that Derivative would stop chasing after his past, so he readily accepted.

Seven o'clock in summer is the switching point between day and night.

The two just went down the stairs while chatting.By the time we got to the bottom of the office, it was already completely dark.The trees next to the office were lush and tall, and a row of street lights had already been lit, illuminating the twisted tree shadows on the ground like ghosts, adding a bit of coldness to the hot night.

The car is Derivative's car, and Derivative acts as the driver on his own initiative, turns on the navigation, and the car drives towards the home of Function—a community.Then the two of them started chatting with each other in the car.This chat subverted the effect of the function on the derivative. He found that the derivative was not too conservative. He seemed to be disgusted with online social media.
