While the boy and his father were watching in wide-eyed amazement, an elderly woman in a wheel chair rolled up to the moving walls and pressed a button. The walls opened and the lady rolled between them into a small room. Then the walls closed and the boy and his father watched small numbers light up, one after the other, high up on the wall.
They continued to watch the numbers light up in descending order, and then the walls opened up again, and out stepped a beautiful young woman.
The father said to his son, "Go get your Mother."
