Yearly reckoning

I didn't write a Christmas letter last year, but this year I plan to after all. It's funny how I don't really remember much before May. Is it possible that the human memory only stays vivid for about six months? The other possibility is that these things are being stored for when I am old. Then I will have lightning-fast recall of every thrilling detail of the Barack Obama primary season, but way more of those moments of walking into a room and forgetting what I came in there for. That's right, I said MORE. I definitely do that all the time now, as it is.
