In my working days, when I had a screw-up in a non-computer capacity, I often found my head immediately jumping to that impulse to hit command-Z, which in computerland, is the “undo” command.
These days I find myself with a new impulse. Sometimes my focus slips, and I miss what someone just said, and I want to hit that magic button on TiVO that rewinds everything five seconds. If I can rewind Oprah, the most powerful woman in the universe, surely I should be able to rewind what the checker at the grocery store just said to me.
