Butterfly Effect

No, not the movie. I love theorizing about this. How one single thing can change your whole life and others as well. Take today for instance. If we'd left 5 minutes earlier or later, taken a different route, if I hadn't had a dentist appointment today, etc and so on, we wouldn't have had that accident. Never mind what all he might have done differently. And let's say we hadn't been there but he did the same thing. Would he have gone into oncoming traffic and been hurt worse or killed? I love talking about this but most people just brush me off. I find it all fascinating.
