The all-round housekeeper is a stick

Lin Mumu didn't go home to call anyone, she went back to borrow a cart. That morning, when Lin Mumu came out of her house and reached the entrance of the alley, she saw an old man pushing a cart with great difficulty, so she went over to help.

A cart of honeycomb coal was delivered to the old man's house, and then I accompanied the old man to move another cart.

Of course, this help was not out of kindness on Lin Mumu's part. Helping to push the cart a little and walk over the small slope was a kindness on Lin Mumu's part, but if he helped to move the cart again, it would be the reward that Lin Mumu had agreed to lend the cart to.

Lin Mumu thought that the wooden boards could only be delivered the next day or the day after tomorrow, but he didn't expect that he could trade them today.

Lin Mumu ran to the old man's house and knocked gently on the open gate. Only after hearing Grandpa Sheng's voice did he enter the yard.

"Grandpa Sheng, I need to use the cart now. Is it convenient for me to lend it to you now?" Lin Mumu and Old Man Sheng agreed that when their family didn't need the cart in the next two days, he would lend it to her.

When Old Man Sheng saw her, he pointed at the cart and said with a smile, "It's convenient, convenient. Push it over and use it. Do you need my help?" After all, Lin Mumu was not much taller than the cart.

Even though their cart was relatively small, it was still tall enough for a child like Lin Mumu.

Lin Mumu shook his head and said no, without taking off the backpack, he pushed the cart out.

When they arrived at the agreed location, Tian Youlu was already there, with two children and an old lady standing beside him.

"Grandma, that's her." Tian Youlu ran over to Lin Mumu and asked, "Why did you come here pushing a cart by yourself? Where's your parents?"

Don’t tell me you’re kidding them and don’t want to pay them, right?

"I can push it myself, why do I need an adult to come? I have brought the money, let me take a look at the wooden boards first." After saying that, Lin Mumu went to the pile of wooden boards to check.

The most she would do is check the thickness and whether the wood board is good, but she doesn't really know how to tell.

But it doesn't matter. She doesn't understand, but Bangchui does.

"Bangchui, do these boards meet the standards?"

The system mallet asked Lin Mumu to touch each piece of wood, and after that gave her a positive answer.

"However, the standard dimensions of the wood board aren't quite right for the data you provided. They're off by a few centimeters. But judging by the diagram you drew yesterday, it should work." The system was referring to the diagram Lin Mumu had casually drawn after completing his study. It was a combination of a children's tricycle and a sidecar bicycle.

However, there are almost no sidecar bicycles in the urban area where Lin Mumu and her friends live. If her model is produced, it will probably be very popular.

"Some of the pieces are the wrong size. Do you want to give me some more boards or reduce the price a bit? 12 dollars?"

Knowing that the size was wrong, Lin Mumu lowered the price a little. She had originally planned to bargain to avoid being taken advantage of by Tian Youlu and the others.

"What's wrong? They were all sawed for you according to the dimensions you wrote yesterday." Tian Youlu didn't know that the dimensions of the wooden boards at home had some deviations. He thought that Lin Mumu was unhappy about the snacks exchange method he had just mentioned and was deliberately trying to lower the price.

Lin Mumu asked the system idiot to mark the incorrect sizes with her and also told her how much the size difference was.

Tian Youlu watched Lin Mumu pull out a measuring tape, pull out a piece of wood, and say it was about right. He then took another piece and measured it. He had the paper Lin Mumu had copied down yesterday for comparison.

Seeing that half of the wooden boards were of different sizes, Tian Youlu blushed.

Tian Youhua, who had initially thought this brat was deliberately trying to lower the price and was about to start a fight with Lin Mumu, saw her second brother's expression and leaned over to check the size. She realized something was wrong, and her faith felt a bit shattered. Was this how her father and grandfather did business?

Suddenly I remembered that my good friend Zhang Xiuhua’s family was making a cabinet. She said that one of the dimensions of the cabinet was wrong. After she went home and asked her father, her father said that the cabinet was not the right size. She then ran to argue with Zhang Xiuhua angrily.

Now......

Did she misunderstand Zhang Xiuhua?

Grandma Tian didn't know the size, but when she was picking up the wooden boards yesterday, the old man told her son that if there were a few that were off in size, she would give them a few more as compensation or charge them less.

Now after hearing what Lin Mumu said, she knew that her son definitely didn't give any extra pieces, so she called her grandson and granddaughter back to ask the old man for his opinion, whether to give him some extra pieces of wood or just exchange them at the price the little girl said.

Tian Youxi and Tian Youhua ran very fast, carrying a lot of planks and blocks of wood when they arrived. Probably to prevent them from falling, they tied them up with hemp ropes, each carrying a handful.

"Grandma, Grandpa said these make up for what's missing."

Grandma Tian nodded to indicate that she understood.

Tian Youlu also understood and asked Lin Mumu if he could accept it.

After Lin Mumu "inspected" it, she agreed. She was in a hurry to use the money, and she would not do business with this family again in the future.

After handing the 15 yuan to Grandma Tian, Lin Mumu didn't bother the Tian family and loaded the wooden planks onto the cart by himself. Tian Youlu and Tian Youhua, perhaps feeling embarrassed, both went to help Lin Mumu.

Seeing that his second brother and sister had gone to help, Tian Youxi was not idle either.

After moving, Lin Mumu planned to leave.

Tian Youlu quickly called for help.
