The boy asked, "What is that, father?"
The father (never having seen an elevator) responded, "Son, I have never seen anything like this in my life. I don't know what it is."
"Could it be a time machine?" asked the boy. “I heard about this movie picture show where people leave the earth in shiny vehicles.”
"Praise the Lord", said the father. "There sure are miraculous things in the city."
While the boy and his father were watching with amazement, 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 the small circular numbers above the walls light up. They continued to watch until the last number was reached, and then the numbers began to light in the reverse order.
Finally, the walls opened again and a gorgeous 24-year-old woman stepped out. The father, not taking his eyes off the young woman, said quietly to his son, "Go get your mother."
