Another observation about video games, if I may.
Let us imagine a situation in which you are playing Prince of Persia, and you push the “rewind time” button and nothing happens and you fall to your death. You yell something like “Crap, my sand! What happened to my sand?”
Let us further postulate that you were previously out of the room for a few minutes leading up to this, and the Arlene next to you says “What sand?”. So you explain the mechanics of the game, and she says “Is that the part where the screen goes dark for a little bit?”, and you say “It would be that bit, yes”.
When she says “I don’t know”. that would be a lie. She knows.
