My Sister is Very Obsessive

After finishing the call with my sister, it was already half past nine.

I ran to the balcony and looked out the window. The sky was very bright, and the rain was much less like a cow's hair.

"Forget it, no umbrella."

After muttering in a low voice, I turned off the lights and doors of the dormitory, and ran to the teaching building in the rain.

When I ran past the small shop, I bought a piece of bread and a carton of milk as I did yesterday.

When the aunt at the canteen saw me rushing in the rain, she kindly recommended me to buy another umbrella. I was also a little moved, and felt that buying an umbrella was nothing.

"How much?"

"thirty!"

The auntie in the canteen handed me an umbrella with a smile on her face.

I took a look at the material of the umbrella, and I lost all interest in connecting with her. For her umbrella, ten dollars outside would be considered too expensive by others.

It's not like this is the case for cheating people. Watching the rain, they will increase the price wildly, and they don't even look at the price and quality of their umbrellas.

"never mind!"

I waved my hands with little interest, and continued on my way in the rain.

This commissary is too cunning to do business, I guess I will never come to spend with her again in the future.

It is said that businessmen value profits, but in fact, the descendants of the real big businessmen’s families are more interested in integrity.

It may not be a big problem to do a small business, but if you want to expand your business, integrity must be the cornerstone of your business.

When I got to the classroom, the practical girl had already taken her place. As soon as I entered the classroom, she waved to me, and as soon as I walked over and sat down, she couldn't help laughing and asked me, where did I go to steal the sugar? .

I looked at her dumbfounded, not knowing what she was talking about.

So she took out her phone, patted my head, then held it up and shook it in front of my eyes.

Looking at the bright white water droplets on my phone, even Shenliu Li, who basically didn't speak much, couldn't help laughing and teasing me.

"If you enter the supermarket like this, other security guards will think you stole sugar and stop you from coming out."

Xia Xiaoman couldn't help but chuckle, then took out a tissue from his pocket, handed it to me, held up his mobile phone, and took several pictures of me from different angles.

I reached out and touched the water droplets on my head. After taking the photo, Xia Xiaoman pushed me in dissatisfaction.

"Oh, you splashed all over me."

"It's just rain, it's clean, is it necessary to dislike it so much!"

"The rain is clean, but your hair is not clean!"

"I washed my hair this morning, okay?"

"It's dirty even after washing!"

Seeing the look of disgust on the face of the practical girl, I couldn't help but give her a blank look, and I didn't bother to care about her anymore.

...

...

The computer teacher is a middle-aged man, and since it was the first class, he came earlier.

During the class, he first introduced himself, and it was amazing to hear him introduce himself, so I took the mobile phone and Baidud him.

I went, it was really amazing, he actually participated in the country's "Lunar Exploration Project".

Although it is only one of countless programmers, such a national-level key space project cannot be joined by any programmer.

However, he did not "show off" himself too much. He talked more about the development of computers and the contribution of computers to the progress of human civilization.

However, he is very similar to our class guide in that he likes to cook chicken soup.

He also likes to talk about his hard school experience when he was young, saying that storage technology was not as developed as it is now.

He went from the CD to the U disk of several hundred MB, and then from the U disk of several hundred megabytes, to the current cloud disk, cloud computing, big data and so on.

But in general, his chicken soup is not poisonous. Basically, it is based on his own growth experience, and he tells us about the rapid development of digital technology in recent decades.

For the course "Computer Fundamentals", I am most interested in binary, octal, hexadecimal and so on.

Especially binary, which is the most basic calculation method of computer. It is hard to imagine that only 0 and 1 constitute the digital technology and network world that we are proud of.

However, it is said that the most ideal computer language should be -1, 0 and 1, namely: no, unknown and yes, so that it is more similar to the way of human thinking.

In fact, I originally wanted to major in computer science, but I was pitted by my sister.

...

...

The two classes passed while the teacher was eloquent and spittle.

After class, Xia Xiaoman habitually threw his schoolbag to me.

After I put the book in my bag, I couldn't help laughing and teasing her,

"After tomorrow, you will have two sets of textbooks."

"You think too much, I only have one set," the practical girl squinted at me, "your set has already been sold by me to the housekeeper at a low price."

"You don't have to be so stubborn, I bought it for more than 200 yuan!"

"I sold each copy to the auntie for five yuan," Xia Xiaoman ticked at me. "You can pay another ten yuan for each copy, and I'll buy it back from the auntie for you."

"You're the auntie, right?" I looked at her with a funny face.

"Ahhh-!"

The hard-working girl suddenly swung her arm over, just as I picked up the schoolbag and was about to carry it on my back, then her arm just happened to be on the schoolbag.

"It hurts..."

Looking at the girl who was holding her arm and tears were about to burst out, I couldn't help reaching out and pulling her arm,

"let me see!"

Xia Xiaoman didn't resist, instead he stretched out his arm in front of me, pointing at the red arm,

"It's all red."

I looked at it, and it was just a little red, it shouldn't be a big problem, so I laughed,

"You deserve it, next time I'll put an iron plate in the book."

"You..." Xia Xiaoman stared at me with open eyes, "Forget it, I don't want to talk to you, Liuli, let's go."

After she finished speaking, she took Shen Liuli's arm, raised her head, and left the classroom with a proud demeanor.

...

The rain was a little heavier than before. I was standing under the canopy of the teaching building. Out of the corner of my eyes, there were students who were leaving one after another with umbrellas. Above that shadow in the rain.

Two black and white fakes, blue overalls, and a pair of white flat shoes, she just stood in the rain with an umbrella, and there was only that figure in my eyes, she was the only color in the world in my eyes.

With a smile on my lips, I walked into the rain, under her umbrella, and gently reached out and took the handle of her umbrella.

When I touched her slightly cold little hand, I couldn't help but feel distressed for a while, I held her cold little hand tightly and looked down at her,

"It's raining outside, what are you doing out there!"
