It's possible that the recipient had had mail forwarded, but I have just sent another card to the correct address with an apologetic note. I have also updated the database of addresses and the mailing labels.
As it wasn't raining, I took a rather roundabout way back from the Post Office where I posted the card. There are some narrow back lanes that straggle up the hill behind the town, so I went up one and then found myself at the bottom of the path up through the woods. It's been very wet recently so the path was slippery, but I prefer climbing UP steep slippery paths rather than trying to come down them. And so I had a bit of exercise. Only 1 mile, but a very steep mile.
I've also just bought an Amazon voucher for son's birthday tomorrow and then remembered that the new Ali Brosh book came out a few months ago. I adored Hyperbole and a Half I'd had her new book on pre-order, but it never appeared and eventually I cancelled the pre-order. But now it should be with me in time for Christmas! I have ordered the physical book. I read most of the books I buy in Kindle format, but I think that will be better as an actual book.
Also today I tried the new tea infuser that arrived yesterday along with two packs of Russian Caravan tea. I can now use loose tea and yet make a single mug of tea. Mid-morning and mid-afternoon, I like a cup of tea but can't drink a whole potful.
