Besides being Patriots’ Day, this is also the thirtieth anniversary of my arrival (back) in the United States. Thirty years. Wow. I can’t quite get used to the idea that I’m old enough for an entire era of my life, full of memories, to have ended thirty years ago. My time spent in New Zealand is already far less than my time spent in Massachusetts. In a few years it will be less time than I’ve spent in Lexington, and less than a quarter of my life overall. It’s sad to think that my entire childhood is now so long and far away.
