It's not that either of these occurrences are bad things, mind you. For both my parents these changes in their lives are a blessing. It's just that they hit me out of nowhere; when my friend called me last night to tell his news, I was driving and thought for a moment that I would run into a lightpole.
Maybe it's a good thing that we often are surprised, because in this era in which almost anything is available in seconds online, real life isn't quite as predictable. We need a few shocks along the way, I guess. We get to see that we aren't nearly as wise, brilliant, or knowledgeable as we think we are.
And so life is meant to be surprising. If someone as bizarre as a pudgy unknown Korean singer can appear out of nowhere and make in 2012 the most watched video ever, then what the heck do any of us really know?
