The love of functions and derivatives

This experience had a great impact on Function. It was so big that Function immediately went to a certain treasure and bought a miniature camera to install in the living room, so he felt more at ease.

Then it was another ordinary morning, so ordinary that when the function went down the stairs, he realized that he had forgotten to bring a cooler, and then he had to go to the convenience store downstairs to buy a bottle of C'estbon.

"Two yuan." The cashier boy said to the function.

The function opened WeChat to scan the code, and then took his mineral water bottle from the cashier.There was a raised vein on the cashier's hand. Because of this, Function took another look, and then he found that his skin was very tender, not like the skin of a young man in his 30s, but like an unfamiliar person. Hands Of A Teenager Having Things To Do.

Wait, the cashier changed?

This idea was quickly terminated because the function was going to be late for work, and the function said thank you very politely, and then ran towards the parking lot in two steps.

The sun outside was so bright that it seemed to drive away all the haze.Even through the glass windows of the car, the sunlight shining on Function's face has been weakened a lot, but he can still feel the scorching heat.

The function parks the car in the parking lot at the bottom of the office building, and walks into the elevator of the office building.Function carried a black briefcase on his back, looked at Yibao in his hand, inexplicably flashed in his mind the appearance of the waiter in the convenience store downstairs wearing a black peaked cap, and the cashier boy also wore a black peaked cap today .

When did he start wearing a peaked cap?

Can't remember, just know it's been a while.

Then he suddenly realized a very important thing. A small-cost convenience store simply cannot afford to turn on the air conditioner. Even in summer, today's cashier still wears a mask.

Function doesn't know when the cashier boy started wearing a mask, so he doesn't remember the cashier boy's face at all.

In the summer of June, a chill suddenly burst from the soles of the feet to the limbs.

No no no stop!

The function comforts itself: What if someone catches a cold?

When I arrived at the office, the function put the bag away, sat down, and received a bombarding QQ message.

Probability: yes! ! ! ! !

Probability: handsome guy, big handsome guy, do me a favor hehe

Probability: /Who are you chatting with and don't reply me.jpg/

Probability: /Smelly man who does not reply to messages.jpg/

Probability: /If I have to cry, will you talk to me.jpg/

Function has no time to worry, he was amused by the emoji of probability, and then returned an emoji with his backhand.

Function: /tsk tsk tsk.jpg/

Function: What's the matter?tell me the story?How are you paid?

Probability: /Strangely Embarrassed.jpg/

Function: forget it

Probability immediately replied with a message: Don't! ! ! ! ! ! ! !

Probability: The mathematics and Chinese proposition groups are tentatively scheduled to have a social gathering in two months, and I want you to pretend to be my boyfriend

Function didn't even think about replying:? ? ? ? ?

function: impossible

Function: /You are making things difficult for me or someone.jpg/

Probability suddenly sent a series of squinting smiles.

Function faintly felt that something was wrong, and sure enough, he received a message of probability in the next second——

I still have a video of you singing in my mobile phone/squinting smile/
