tell me

In the bookstore, two people of similar height stepped onto the escalator one after the other.The people in front looked straight ahead without squinting, while the people in the back looked left and right with sad faces.

The young man behind hesitated for a long time, and finally grabbed his neat short hair, a bit of embarrassment appeared on his wheat-colored face.

"Then what, Brother Du, in fact, you don't need to come with me..."

The person in front stepped down the elevator first, and walked to the "Recommended this month" book list, he picked up a book and simply flipped through it: "It's okay, I'm coming, no matter how I look at it, it's me. You should be thanked."

"Du You, she..." The young man followed closely, his panicked hands had nowhere to rest, so he could only pick up the book and fiddled with it upside down like Du Yu.

"Nan Zhe, you don't have to be so cautious with me. Du You treats you so heartlessly because of getting close to you." Du Yu lifted the basket beside him and turned to ask him, "By the way, are you here?" What book did you buy?"

"Oh, yes, I'm here to buy two textbooks. Our professor of bioinformatics asked us to model and analyze data, but no one taught us, so we can only study by ourselves." Cui Nanzhe seemed to have finally remembered the purpose of this trip, and hurriedly Turn your head to look at the floor classification of the elevator entrance.

"Modeling..."

Du Yu repeated subconsciously, he did know a master, but he didn't know how that person learned it.

"What's the matter, Brother Du?" Cui Nanzhe heard him muttering thoughtfully, and couldn't help turning around in doubt, "Will you do it too?"

"No, I don't know much. I have a friend...someone I know can." He also looked up at the tag, "I'm going to buy children's books, and I'm not on the same floor as you."

When Cui Nanzhe heard this, a gleam of joy finally appeared on his face, which had been stalemate for a long time: "Okay! Then let's split up and meet later."

"No." Du Yu refused him without hesitation, as if it was a matter of principle, "Didn't you tell my sister that you want to find someone to accompany you to the bookstore? I can't complete this task without accompanying you. Together .”

His cold tone carried a toughness that cannot be ignored, and Cui Nanzhe's face wrinkled together again.But Du Yu was born to hold grudges, so he could only follow him upstairs with a sad face.

"Brother Du, why are you buying so many children's books?" Cui Nanzhe wondered as he looked at the fairy tale books Du Yu kept putting in his basket.

At this time Du Yu was pulling out a hardcover edition of "The Little Prince" from the shelf.On the round planet B612 stood a little boy wearing a crown and an orange fox with a big tail. The little boy and the fox looked at each other silently, and the picture was warm and peaceful.He turned over to look at the price, thought for a moment and threw the book into the basket.

"To support education." He replied without looking back.

"Oh, support teacher, where are you going?"

"City H."

"There, the conditions there are not very good. Some of my classmates went there, and they cried to death when they came back."

"Ah."

"Brother Du, do you teach elementary school? What grade do you teach? The fifth and sixth graders don't read fairy tales much anymore. It's better to buy some best-selling novels and classics."

"it is good."

"You can also buy a few books like Sudoku or brain teasers to liven up the atmosphere...Brother, which class do you teach?"

"Language."

"I think so. Hey, don't buy too much, the school only reimburses a little."

"Ah."

"Doo..."

"Say."

"Your sister, I mean Du You, she..."

"It's almost ok here, go to the opposite side and have a look."

"Oh, well..."

Cui Nanzhe sighed and followed behind in despair.

After picking out novels, Du Yu also added two picture albums.In order to express his gratitude to Cui Nanzhe for his suggestion, Du Yu invited him to have dessert in the cafe of the bookstore.

He watched the young man on the opposite side trying to make an elegant posture, and gently stroked the blue glass containing lemonade with his fingertips.

"Do you like Du You?" He said slowly, his voice was not loud but he examined it carefully.

Cui Nanzhe stopped eating the cake suddenly, he coughed twice and poured a glass of water down his throat: "No...no."

"That's good." Du Yu took a sip of water, and his wet lips left a string of light blue water marks on the rim of the cup. "My sister doesn't like you very much."

When Cui Nanzhe heard this, he simply stopped eating.He poked the spoon into the cake and pulled it out, pulled it out and poked it in again, and after a dozen seconds of silence, he stammered, "Oh... yes... yes."

"Yes, she said she watched you hit you once." Du Yu put down the water glass, and the bottom of the glass collided with the table and made a clear sound, "But of course I will not allow her to do this, after all, you are also our benefactor."

"Haha..." The young man laughed awkwardly, "No, Brother Du has also had a great influence on me. Without you, I wouldn't be where I am today. I have to thank you."

"Du You is going to take the college entrance examination," Du Yu said suddenly, like the surface of water in a glass without any waves, "I will trouble you to take care of her this year."

"For sure, my parents regard her as more important than me now, she is long and short in front of me every day, absolutely nothing will go wrong." Cui Nanzhe nodded his head.

"Too serious, we are always outsiders. Du You said that when you were not around, your uncles and aunts often mentioned you, and even complained that you didn't call them."

"Hehe, the lab is endlessly busy. But in fact..." He rubbed the plastic spoon handle, "Forget it, I don't really have anything to say, maybe girls are more filial."

"As long as you want, you can do it too. Cherish it." Du Yu knocked on the table to break the slightly heavy atmosphere, "Have you finished eating? Let's go after eating. I still want to buy your book."

Cui Nanzhe scooped up the last piece of cake and stuffed it into his mouth. With a "hmm" sound in his throat, he followed Du Yu and got up with his backpack.

"Oh! It's expensive, and I don't know which one to buy." Cui Nanzhe compared the two textbooks in his hand, turned his head and whispered to Du Yu who was standing next to him, "Brother Du, do you know which one to buy? Don't you know this? My friend, help me ask?"

Du Yu didn't want to talk to Lu Yinke, and felt that the books should be similar, so he replied casually: "That person is not very good, so it's useless to talk to him."

"It's pretty good. The national first prize is nothing more. I mainly rely on my teammates. I paddled the whole way." A lazy voice came from behind, and then a bony finger hooked the edge of a thick book in the corner of the bookshelf. , The book fell into the big hand along with the force.

He patted the cover and put the book in Cui Nanzhe's hand: "Just read this book at the entry level. The classification is clear and easy to understand. Although I don't know what you are using it for analysis, but this book is the foundation for modeling. Exactly."

Cui Nanzhe looked blankly at the book in his hand and at the person in front of him, then he slowly turned his head to look at Du Yu: "Brother Du...do you know each other?"

Du Yu glanced back with his neck sideways, and nodded with a grim expression.

"Well, I'm Brother Du's friend Cui Nanzhe, thank you for recommending the book to me." Cui Nanzhe put the book under his arm, hurriedly rubbed his hands together and stretched them out. The serious handshake gesture was like meeting the leaders of the two parties.

"Are you his friend?" Lu Yinke was talking to Cui Nanzhe, but his eyes were fixed on Du Yu who was next to him, his eagle-like eyes seemed to penetrate the flesh and directly penetrate the man's heart.

He lazily stretched out his hand from his pocket and gave Cui Nanzhe a symbolic shake twice: "Miangui's surname is Lu, Zichou Yinmao's Yin, Nanke Yimeng's Ke."

"Yeah, yeah, we've known each other for many years." Cui Nanzhe nodded hurriedly, "Let's think about it, it's been almost ten years?"

Lu Yinke raised his eyebrows, and his tone of voice was obviously surprised: "It's been so long?"

"Brother Du, he lives..." Cui Nanzhe swallowed temporarily, "He often comes to my house to play."

"Well," Lu Yinke nodded and put his hands back into his pockets again, "I'm his college classmate, and I took Du You to the amusement park a few days ago."

"Oh, I know, I know, they came back very late that day, and Du You even showed off to me..." Cui Nanzhe's eyes suddenly widened, full of admiration, "You are the one who gave Du Ge a gift and Du Ge took it? Dude, you are really amazing!"

"Nan Zhe." Du Yu shouted from the side, accusing and dissatisfied.

"Don't wait, Chairman Du, please don't be angry." Lu Yinke patted Cui Nanzhe on the shoulder, "Little brother, why do you know everything? You even know exactly when they will come back."

Although I don't know why, Cui Nanzhe became nervous for no reason.Whether it's from Du Yu's roll call, the tone of the person in front of him, or the appearance that Du Yu didn't want to mention at the beginning, he can clearly feel that there seems to be a storm brewing, and he must not intervene, because it is It belongs to the game of two big men.

So he blinked his eyes twice and decided to pretend to be dumb: "Uh...it's a neighbor, you can hear the door closing."

Lu Yinke nodded thoughtfully again.

"Why are you here?" Seeing that their chat had come to an end, Du Yu finally opened his mouth impatiently.

"Why, no matter what, is the bookstore your home?" The other party asked back.

Du Yu frowned. It had been a long time since he heard Lu Yinke's tone so aggressive.But thinking back carefully, Lu Yinke seemed to be just joking in the past, and it was the first time that he was really open-minded.

Perhaps Lu Yinke was also aware of the anger hidden under his words, before he could understand, he sniffed and turned his head to explain: "I often stay here during holidays, and I have read almost all the books in this cabinet. it a accident."

"Well...do you need anything else? I can help with computers." As if to relieve the tense atmosphere like a rubber band, Lu Yinke turned to Cui Nanzhe.

Cui Nanzhe was flattered, but he didn't take advantage of his acquaintances, so he forgot for a moment that he was in dire straits, happily added a big brother friend, and happily turned around to pay the bill.There were only two people with their own concerns left in the narrow aisle.

Lu Yinke glanced over the heavy plastic bag in Du Yu's hand.

"Here, do you need my help?" He hesitated and opened his mouth.

"No need." Du Yu raised his head and glanced at him, two words popped out of his mouth lightly, bouncing like glass beads and rolling into the distance.
