It's really. really simple... This lady is bored because she has been left holding someone's iceream for so long. She started pretending she was a train robber and now she is performing it in a mirror. Can YOU really, really explain it any better than me?
better yet, from the first ten years of my life (1948 - 1958) when calculators were mechanical, and radios and tv's were all vacuum tubes. a computer was something so exotic only governments are really big corporations had anything like them, and almost no one else had any idea what they were, phones were landlines, party line service, and some still had cranks on them, or batteries the size of 12 oz beer cans. and the fosters franchise was the only place you could get 'soft serve ice cream". oh how i wished at the time i could show people something like this, when they didn't believe a computer would ever be anything more then a bizaarly complex adding machine, and why would anyone ever want one, while i was dreaming someday, we would be making pictures on them, and humans would set foot on the moon and send computer driven machines to land on and explore mars. i mean our whole world today, people thought you were nuts to believe anything like it would ever become possible.
