Back when I was 9 years old, I devised a foolproof survival plan in the event of a home invasion. It was a masterpiece. It took into account every eventuality.
Mind you, my neighborhood was not an especially dangerous one. It’s not like there were reports of these things happening to our friends or relatives. To my knowledge there hadn’t been so much as a bike stolen off a porch, so I’m not sure why I thought there was a need for a plan. Maybe I saw something in a movie or TV show? In any case, if it ever did happen to us, I was prepared.
