One day I asked if my Mom could shut down my computer. I told her to press "the
big gray switch on the computer." After some time, I phoned her and asked if she
shut the machine down, but she replied, saying there wasn't any big gray switch
on the keyboard.
Me: "No, Mom, not on the keyboard; it's on the computer."
My Mother: "Computer?"
Me: "Yes, that gray box on the floor."
My Mother: "Ah, the engine!"
My Mother: "Yes, it's making lots of noise."
