A young man wants to work and make some money. He goes to a factory. It is his first day at work. The head of the factory says hello to the young man with a smile. Then he gives him a brush. The young man must clean the floor.
The young man doesn’t understand and he says, “But I studied at university.” The head of the factory then says, “Oh, I’m sorry. I didn’t know that you studied at university. Give me the brush, and I will show you how to do it.”
