Once upon a time, there was a squirrel who was both rich and stupid.
One time, it saw that White Rabbit had a three-story building, and wanted to build one too, so it hired an engineer to build the house. The engineer thought: He might do something stupid. Although I thought so, I said yes. So, the engineer began to lay the foundation... One day, the squirrel came to inspect and asked the engineer what he was doing. The engineer said he was building the first floor. The squirrel said: "Instead of the first and second floors, we want the third floor." ”The engineer shook his head and left.
Children, do you know why this is?
