It’s what he would want.
With reasonable care and a hell of a lot of luck you might last another ten years, or five years, or two years, or six months, but then of course again on the other hand as I’m sure you’ll appreciate trying to be completely objective about the matter you might not. So in future, if there is any, every birthday is going to have a lot of things about it that make it feel like your last one, and the same with every evening out, and after four of your five years or five of your six months the same with most things, up to and including getting into bed and waking up and the rest of it. So whichever way it turns out…it’s going to be difficult to feel you’ve won, and I don’t know which is worse, but I do know there’s enough about either of them to make you wish you could switch to the other for a bit. And it’s knowing that every day it’s more and more likely that one or the other of them will start tomorrow morning that makes the whole business so riveting.
