Sunday, Sun Yanqing had just had breakfast when the doorbell rang. Sun Yanqing opened the door and said, "It's the second brother, come in, come in!" Someone came in with a bag.

The person who came and Sun Yanqing were in the same village as Sun Yanqing's family, and Sun Yanqing was a few years old, so Sun Yanqing called him the second brother. As soon as the second brother entered the door, he put down the bag in his hand, which contained more than ten catties of chestnuts. He exchanged a few words with Sun Yanqing and began to explain the purpose of his visit. It turned out that his son got married this year, and the woman asked for a bride price of 50,000 yuan. He borrowed almost all over the village before he collected 30,000 yuan. It was really useless, so he remembered to borrow it from Yan Sunqing. Sun Yanqing was about to agree, but his wife Liu Meili winked at him, pinched her mouth in the bedroom, and said, "Come here!"

Sun Yanqing went to the bedroom, and Liu Meili closed the door and said that the money could never be borrowed. He said that a farmer, in addition to farming, does not go out to work, when will he be able to pay back 20,000 yuan. Sun Yanqing told her about their friendship, but Liu Meili was still reluctant and said, "How much is the friendship worth?" Sun Yanqing said, "Don't you always want me to smoke? I really can't, I will quit from tomorrow, as long as you let me lend money to my second brother, how about it?" Sun Yanqing was eloquent, and after a lot of effort, Liu Meili finally agreed.

Sun Yanqing took out 20,000 yuan and handed it to the second brother, who was very excited and shivered with gratitude. At this time, Liu Meili handed a piece of paper and a pen and said, "Second brother, I lent you the money, and we don't want interest. You can open an IOU!" The second brother was stunned for a moment. Sun Yanqing understood what he meant. In their hometown, who built a wall and built a house to marry a daughter-in-law? When they are rich, it is very common to borrow money from relatives and neighbors, and they have never said IOU.

At the moment, Sun Yanqing said, "What kind of IOU, the second brother is not an outsider." Before Sun Yanqing could finish speaking, Liu Meili glared at him and motioned him to shut up. At this time, the second brother said, "My brother-in-law is right, my brother will settle the bill clearly, and I should issue an IOU!" So he bent down, wrote an IOU on the coffee table, and handed it to Liu Meili.

One day, a few months later, as soon as Sun Yanqing got off work, Liu Meili asked him anxiously, "Did you touch the drawer in the big closet?" Sun Yanqing shook his head and asked what was wrong. Liu Meili said, "I clearly put the second brother's IOU in the drawer, why did it disappear?" Sun Yanqing said, "Yes, if I hadn't let the second brother hit that IOU in the first place, this would have happened!" Liu Meili knew that she was in trouble and kept silent.

A few days later, Sun Yanqing came home from work and heard Liu Meili humming a tune in the kitchen. When she saw Sun Yanqing, she said, "The IOU is back!" Sun Yanqing teased: "Is the IOU back? It ran back by itself with legs?" Liu Meili said, "Don't joke, the IOU is really back!"

After Liu Meili finished speaking, she wiped her hands and went into the back room. After a while, she held a note in her hand, and Sun Yanqing took it and saw that it was indeed the IOU written by the second brother. He looked surprised and asked, "This... what's going on?"

Liu Meili told the story. It turned out that Liu Meili's best friend Xiao Zhao had a cousin who opened a painting and calligraphy club and was good at imitating other people's handwriting. Liu Meili took a photo of her second brother's IOU and asked Xiao Zhao to imitate it.

Sun Yanqing shook her head and said, "The handwriting of this IOU looks very similar to that of the second brother, but don't you know that the Public Security Bureau has the technology of handwriting identification? As long as it is not written by yourself, they will know the authenticity as soon as they test it. At that time, not only will you lose your money, but you will also be charged with forging evidence, and you will not be able to eat it!"

Liu Meili was at a loss. Sun Yanqing said, "Tear up this IOU and treat it as if the 20,000 yuan was lost. I will work hard in the future and try to get more annual bonuses to make up for this shortage." Liu Meili suddenly thought of something and said, "I said my surname is Sun, why do I think you don't want the money! I don't care, Brother Wan 12i can't see it." She insisted on putting away the fake IOU.

A year later, the second brother came to Sun Yanqing's house excitedly. As soon as he entered the door, he said that his family had a bumper harvest of chestnuts this year, and the price was good. He sold it for tens of thousands. This time, he came to return Sun Yanqing's money.

As soon as Liu Meili heard that, she went to the back room to get the IOU. After a while, the back room let out a cry. Sun Yanqing didn't know what happened, so she went into the room to see, but Liu Meili's face turned yellow and her eyes straightened, and she stayed there. Sun Yanqing hurriedly asked, "What's wrong?" Liu Meili said in a trembling voice, "The IOU, the IOU is lost again!" Sun Yanqing said, "You are so lost, how can I say hello." Liu Meili said, "This second brother is here, what do you say?" Sun Yanqing said, "I have to tell the truth."

The couple went out of the inner door, and the second brother asked, "What happened just now?" Sun Yanqing said, "Second brother, we lost the IOU you wrote!" Second brother said, "What's the big deal, I'll lose it if I lose it!" After saying that, the second brother took out a thick paper bag from the bag with him, handed it to Sun Yanqing, and said, "This is 20,000 yuan, you count it!" Liu Meili grabbed it and said, "It's all a family, what else do you count, we believe in the second brother!" Then the second brother and Sun Yanqing talked a few words about family affairs, and said that they had to rush home to the car, so they turned and left, and Sun Yanqing followed him to see him off.

On the way, Sun Yanqing said, "Second brother, I threw away the IOU as soon as you left the front foot, and I didn't plan to ask you for it at all..." Second brother said, "How can that be? Who are you when your second brother is!" Sun Yanqing said, "I am here to atone for my sins!" Second brother asked, "What crime to atone for? As a college student, you are knowledgeable and reasonable, what crime would you commit?" Sun Yanqing said, "There is a tea garden in front of our village. In winter, the people who contract the tea garden will prepare a lot of grass curtains to keep the tea trees warm. In the winter of 1991, a fire broke out on the grass curtain stack and half of it burned. Do you remember this?" Second brother smiled: "Remember." Sun Yanqing said, "In fact, I set the fire. That summer, Wu Datou and my father had a dispute over farming and beat my father up. To vent my anger, I set his haystack on fire. After lighting it, I saw that the fire was getting bigger and bigger, and I was very afraid that the police would arrest me, and then I would be finished. But then I heard that Wu Datou said that you set the fire, and your father beat you up and paid Wu Datou a thousand yuan." The second brother said, "In fact, I always knew that you set the fire, and I saw when you set the fire!"

Sun Yanqing almost jumped up and said, "You knew it earlier? Why didn't you expose me at that time?" The second brother said, "My father and Wu Datou have a good relationship. I admit that I started the fire, and my father also beat me and paid some money. You are different. You are always first in the grade, and I know you will definitely have a future. How can I let a fire ruin your life?"

For a moment, shock, shame, and emotion surged into Sun Yanqing's heart. He opened his mouth, but couldn't say a word. He could only shout in a low voice, "Second brother..."
