The mother's ashes were packed in an urn and carried all the way home, and Ding Zhengxin sent his nephew to the door of the community without entering. Chen Siping's hands were empty, he glanced back at his uncle, nodded goodbye, and many words were silent, leaving a lonely back.

Chen Siping became an orphan, his uncle was his only relative, Ding Zhengxin saw him go, thinking about taking care of him in the future.

Back at home, Chen Siping covered a white cloth on the dining table as a sacrificial table, put his mother's urn, looked at it a few times, felt cold, and his nose was a little sour. After thinking about it for a while, he hurried out again, went to the nearby small commodity market to buy ceramic incense burners and incense candle fruit plates, passed by the fruit store to buy apples and oranges, passed by the dim sum shop and bought steamed buns and square cakes, and carried them home in large bags and small bags.

On the sacrificial table, incense and candles were lit, fruits and snacks were placed, and Chen Siping looked at it silently for a moment, folded his hands and bowed a few times, and went to the kitchen to boil water and make tea. After the water boiled and the tea was brewed, he ate two steamed buns with mustard vegetables, peeled an orange to eat, and padded his stomach.

It was already afternoon, the house was quiet, Chen Siping returned to his room, looked at the book left by his father, and suddenly lost the courage to open it.

A thought popped into my head. He felt a slight dizziness, like a lack of oxygen to his brain after a long run, and his heart was beating hard.

The fear of death, the escape from the world, and the thirst for self prompted the father to make up his mind to abandon his wife and children, cruelly cut off the past, carry selfishness and indifference, and leave the country alone, in a city where no one knows, and spend the rest of his life peacefully. One day, death will come, there is no escape, nothing can comfort him, life is the sand in the hand, the tighter the grip, the faster it will drain...... But he couldn't forgive himself. So my father left these books with a slim hope, hoping that one day, Chen Siping would be able to find his own answers from these books, instead of living in a mess like his mother and many people.

He lived up to his father, he read the books left by his father, followed his footsteps, and looked for him, but the death of his mother changed everything, and at this moment, his father really died in his heart.

Chen Siping cleared out a layer of bookshelves, put his father's books on them one by one, and handled them lightly, like fragile porcelain, neatly and meticulously. It was a piece of my father's past, and it was a part of his past. Now, it's time to say goodbye to the past.

For the rest of the winter vacation, Chen Siping lived a calm life, giving his mother a stick of incense every morning and evening, the candles were not lit, the smoke was uncomfortable, the fruits and snacks were eaten, there was nothing to do, nothing was wanted to do, watching TV all day long, and not even missing advertisements. It's just a mess, eating, sleeping, eating, and not going out for a walk, and when the new semester starts, Chen Siping looks fat.

Director Lu of the Teaching Office is well-informed, and heard some rumors, Chen Siping is also a person with a bit of background, Ding Zhengxin of Surabaya Middle School specially greeted their principal, the library is short of people, and he asked him to help. Ding Zhengxin is an old classmate of the principal of Songjiang Middle School, and he can usually speak, a temporary worker, there is no need to alarm the principal, but Chen Siping is a little special, he is Ding Zhengxin's nephew, his mother passed away in the first few years, and his mood may not be very stable.

With this relationship, it is inconvenient for Director Lu to summon Chen Siping to death.

Everything is back to the starting point, Chen Siping commutes to work normally, stays in the storage room, and has a lot of free time except for helping out in the library. It's not always a matter to be in a daze alone, the spirit is empty, and Ji Xi raised his head from the silence, and he couldn't help but want to find a book to read.

Chen Siping walked around the library shelves and finally picked up a copy of "The Evolution of Desire", written by David M. Bass, who talks about evolutionary psychology, "using the theory of evolution to explain human behavior, focusing on human sexual psychology and its relationship with what Darwin called sexual selection", which should be interesting.

No one disturbs, you can read quietly, after a year and a half of baptism, Chen Siping's reading ability has made great progress, although at the beginning of the bumps, not very accustomed to it, soon read into it, every time there is a heart, I can't help but smile. Occasionally, he would be proud of himself, a book that even his father had never read, and on his way to catch up with him, he finally saw a new landscape with him.

Based on his shallow life experience, women sometimes exhibit irrational, moody emotions, as evolutionary psychology explains, "Being with a moody partner can be costly, and they will use up a lot of your time and energy." To soothe them, put aside your plans for a while to help them get rid of their bad moods, which will use up energy that should be spent on other things. Women use this cost-increasing tactic to induce men to make commitments. A moody woman would say something like: 'You'd better make a promise to me, or I'll make you pay with my capricious emotions.' This is one of the many means by which women induce men to make commitments. But men don't like it, because it drains them of energy that they should be using elsewhere. ”

"Moodiness is also used as an evaluation tool to test emotional bonds. Women will use their moodiness to make men pay a small price, and then evaluate their commitment by how men react to that price. Men's reluctance to bear this price is an indication of their low level of commitment. Men are willing to bear the cost and are sensitive to the requirements attached to these investments, indicating a high level of commitment to the relationship. Either of these means can help women get important information about the strength of their bonds. ”

As the party that invests more in the reproduction of both sexes, it is an unconscious strategy for women to subjectively assess men's "level of commitment to affection" through "moody" behavior, and objectively consume men's "time and energy" to ensure that the reproductive resources invested or will be invested (conception, childbirth, care, nurturing and protecting young children, etc.) are maximized (survival and reproductive advantages of offspring). Therefore, when women are moody or even vexatious, they need comfort, companionship, and attention, rather than rational analysis or "one to calm down."

"Failure to understand the true and absurd nature of human mate selection can cost us dearly, both in a scientific and social sense."

Chen Siping felt that he had gained a lot.
