As my wife and I pointedly reminisce about the events of 20 years ago, our children look at us with expressions of dim comprehension. My 12-year-old can no more envision a modern city divided by a wall than I, as a 12-year-old, could envision that wall ever coming down. The temptation is to impart all sorts of "lessons" during this moment, but where does one even begin?
So far the only summary we can muster is, the world is in a constant state of flux, often moving in ways we can't even begin to predict. So many changes are violent and lamentable, but there are also momentous changes that are welcome, and to be celebrated. Here's hoping our children live to see -- and generate -- more of the latter.
