A little peasant boy and his father were visiting a shopping center. They were stunned by almost everything they saw, and especially by two bright silver-colored walls that could open in half and close. The little boy asked, "What is it, Father?"
The father, having never seen a lift before, said, "Son, I have never seen anything like this in my life, I do not know what it is."
As the boy and his father watched in admiration, an old woman in a wheelchair goes walls and pressed the button. The walls opened and the lady rolled into the small room.
The walls closed and the boy and his father watched the numbers scroll sequentially on a dial above the walls. They kept looking until the numbers began to scroll in reverse order. The walls opened again and a very beautiful 24-year-old woman came out.
The father, unable to look up from the young woman, whispered to her son, "Go get your mother."
