Oh, NudeJude, you have to put something up for Christmas! It doesn't have to be a lot. But just one or two 'bits' to remind you that it's Christmas. Get a small, inexpensive ready-lit tree - a few baubles here and there, a couple of lovely candles ...? For YOU TWO. You're important! And there's nothing nicer than settling down to watch the TV with all the Christmas lights on!
You say that you won't be seeing your family over the holiday period - but could you invite a couple of neighbours in, say, on Christmas Eve, for a Baileys or two & a mince pie?
Whatever you decide, HAPPY CHRISTMAS! to you.
