After the meal was full, Zhang Yuan and several staff members packed up everything, cleaned the whole kitchen carefully again, and left the restaurant a little tired.

He suddenly felt someone patting him on the shoulder.

Looking back, it's Lin Xuanxuan.

Her face was a little ruddy, and she didn't look so upset at first.

Lin Xuanxuan asked, "are you a little tired?"

"It's OK. It's exercise."

"Well, let's go for a walk in the botanical garden. I feel like I'm eating a bit."

Zhang Yuan thought about it and nodded.

At present, the most popular place on the earth times is the botanical garden, where there are all kinds of functional plants, full of green, and the air is the freshest.

In low gravity environment, in order to make plants grow in an orderly way, scientists have designed a special space device to fix the plant in the substrate, so that it can grow in a reasonable way.

They walked shoulder to shoulder, enjoying the fresh and natural air.

Lin Xuanxuan suddenly said, "I just woke up from hibernation. How can I forget the past? Sometimes suddenly think of, or will be very uncomfortable. It's been a good day, though. "

Zhang Yuan sat on the steps, "let me tell you a story..."

"Good." Lin Xuanxuan also sat down.

"I once had a good friend in high school. After graduation, we went to different universities. At first, we kept in touch with each other. Later, our life circle gradually changed.

"I can't understand his circle of friends like an outsider; he doesn't know any of my friends."

"In this way, there is less and less contact with each other."

"How long has it been? It took me so long to forget. When he updated his status again, he sent out a message of blessing. After clicking in to read the comments, he realized that there was a serious illness at home a while ago. "

"So I sent a message to say hello and didn't reply. If it is several times, it will no longer be issued. "

"And then we lost touch."

"I think life, in the end, is a gradual farewell. It's just that sometimes it's hard to make peace. Once a good friend, it's just like this The most important thing is to cherish the present, isn't it? "

Lin Xuanxuan looked at him with her eyes and couldn't help smiling: "sometimes, you are not so straight and poetic..."

Zhang Yuan said with a smile: "how can a person without poetry come to a distant place?"

"True narcissism Do you remember the memo on earth

"I remember." Zhang Yuan recalled: "the most unforgettable thing is to eat a BQ ice-cream. It's so expensive. My heart aches to death."

"You are so mean, just an ice cream!"

Zhang Yuan touched his nose, "I donated all the houses. I'm stingy!"?! I've spent 20000 yuan on this party! "

"Ah, how generous you are!" Lin Xuanxuan changed her words with great exaggeration.

They talked for a long time, missing the past, describing the future

Zhang Yuan suddenly found that he was not as strong as he thought. There were many things, but he was oppressed in his heart. Now he had a vent, and he couldn't bear it, just like opening a floodgate.

And the opposite girl is the same, unconsciously said a lot.

Talking is always the best way to deal with stress.

Soon, the botanical garden will close soon, and the soft music will sound.

Zhang Yuan stood up from the steps.

Lin Xuanxuan suddenly said, "generous and hospitable Mr. Zhang, do you have a feeling of heartache after spending so much money?"

Zhang Yuan replied with a smile: "are you interviewing me now? Are you still a journalist? Can't you? "

"Professional habits. I'm a doctor now. I used to study medicine, but I'm a part-time reporter. Do you really think that our civilization can afford to be a journalist? "

what make complaints about a woman who studies medicine is rather baffling and part-time reporter?

"Doctor? The patient will be tortured to death by your crazy desire to spy! "

Lin Xuanxuan rolled her eyes: "it's called exuberant and intense curiosity. Do you understand? If I am allowed to be a physicist, I will give you PK! "

"I'm just a little curious. Twenty thousand Singapore dollars can be used in the new civilization. It's not an asset on the earth. It has real purchasing power. If it was me, I would be reluctant to invite people to dinner like this... "

"That means I have a high moral character!" Zhang Yuan laughed twice.

"You have a good character?"

Seeing Lin Xuanxuan's puzzled eyes, he was a little embarrassed when he thought of the pain he felt when buying Actually, I don't think it's a big problem to make money in the future. Tens of thousands of yuan. It's drizzle. It's nothing to make everyone happy. "Wait a minute. It's a little too big to say that it's even more inappropriate.

Lin Xuanxuan couldn't help laughing, "you are so narcissistic. If everyone is like you, the society is very simple."

Zhang Yuan honest said: "in fact, the moment I made the decision, I was distressed, but later it returned to normal."

"You say I'm simple, but it's not like this For this plan, I will make this choice after a series of reasonable calculations. "

"If we use scientific language to reasonably explain what I just did, it may be to create a more friendly and harmonious social norm This kind of atmosphere is helpful to everyone's quality of life and can last for a long time. "

"It's really worthwhile to spend 20000 yuan to improve the quality of collective life. I even suggest that such banquets be held regularly in the future. "

Lin Xuanxuan blinked, "do you guys of science and engineering speak so seriously? I remember, you're in the space machinery industry, right? Why do you go to sociology again? "

Zhang Yuan said: "the sociology of the earth civilization is really a liberal arts. But the current new civilization historiography, in fact, is based on the game theory and psychology. In a small society with only such a small population at present, it is not difficult to find the local optimal solution... "

Hearing a lot of technical terms, Lin Xuanxuan felt a little bit big and vomited her tongue.

Zhang Yuan continued: "if there is no overall plan, let it be, human beings will spontaneously choose their current optimal greedy strategy. What is the optimal greedy strategy? Of course, it is to control more resources, seize the most beautiful objects, and raise a large number of younger brothers to consolidate the violent regime. "

"If everyone thinks that way and seeks to maximize their own interests, life will become a mess, full of contradictions and dangers. Have you seen the doomsday? The end result is that except for a few people, everyone's life is not good. This is the classic prisoner's dilemma. "
