As I mentioned earlier, I asked commenter Flabberghasted for money, and he came through. Which left me with a not-terribly-fungible Amazon gift card, and the question of what to do with it.
I wound up taking Shelley’s advice: used the card to knock $50 off my Christmas shopping, and then made a $50 donation to the Secular Student Alliance. Because today’s students are tomorrow’s future that the Terminators will come back in time to try to undo. Or something like that.
