Anyway, I told people a whole year before I left that I was going. That’s a lot of time to say what you have to say, to settle matters and to make your peace with someone. Over the course of the year, I had a few sit-downs with old friends and family and did a final poking of old wounds and ashes; in nearly every case it ended well. A couple of times I asked forgiveness for things I didn’t particularly feel sorry about, and in one case I found myself in bed with someone who otherwise I’d rather I hadn’t. But you do what you have to do to give people closure; it makes them feel better and it doesn’t cost you much to do it. I’d rather apologize for something I didn’t really care about, and leave someone on Earth wishing me well, than to be stubborn and have that someone hoping that some alien would slurp out my brains.
