A boy and his father visiting from a small country village in
Latvia were at a large multi-story shopping mall in America.
They were amazed by almost everything they saw, but especially by
two shiny, silver walls that could move apart and back together
again.
The boy asked his father, "What is this, father?"
The father responded, "Son, I have never seen anything like this
in my life, I don't know what it is!"
While the boy and his father were watching wide-eyed an old lady
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. The walls closed and the boy and his father watched
small circles of lights with numbers above the walls light up.
They continued to watch the circles lit up in the reverse
direction. The walls opened up again and a voluptuous 24-year-old
woman stepped out.
The father said to his son, "Quick! Go get your mother."
