Although children cannot learn well, they can play around in the school. It is one of the best. The teacher will come to the house and let the parents cooperate with the school to educate the children.
The year-end exam is about to come again. In order to encourage the child to study, the old couple called the child in front of him at night and said to the child: “My child, if you reach the middle of the exam this year, I will buy you what you want.”

The child looked at his parents, tilted his head and said, “I like horses. When you watch TV, people ride on horses. How majestic!”
My child, there are no horse riders now. I bought cars. When you grow up, I will buy you a car. “
“No, I want a horse, I want a horse now.”
“That horse is only worth a few dollars. The money to buy a car requires several horses.” Lao Sun’s wife said.
“I don’t want a car, I want a horse!”
“Okay, it’s a deal. When you finish the exam, I will buy you a pony to keep it.”
The child jumped up happily and said: “I want a BMW!”
The old couple was stunned.
