An Antartian boy and his father were visiting a mall. 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 [never having seen an elevator] 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 light up in the reverse direction.
The walls opened up again and a beautiful 24-year-old woman stepped out. The father said to his son, "Go get your mother."

一个男孩和他父亲一起在逛一家大型商场.他们对所看到的所有东西都感到惊奇,特别是二扇闪闪发光的银色的门,可以自动开启和闭合.男孩问父亲,"爸爸,哪是什么?"父亲(从来没有看到过电梯)回答:"儿子,我也从来没看到过这个东西,我不知道这是什么." 正当父子俩睁着眼睛看的时候,有个坐轮椅的老妇人来到活动门前,按了一个按钮,门打开了,妇人转动轮椅进了一个小房间.

门关闭了,男孩和父亲看到墙上有显着数字的小光圈从下到上地闪动着,他们又继续注意到那个小光圈的数字朝着相反的方向闪动着,然后门打开了,出来一个24岁左右的美丽女子.于是父亲对他儿子说,"走,去把你妈叫来!"
