We Brits have all but forgotten about Twelfth Night- which is a pity. The more festivals one has at this time of year the better. I don't do well in the cold. This house is well heated but the icicles still get through. I've been wearing a scarf indoors. A lovely long, fluffy woollen scarf.
But about Twelfth Night. It was still a bit of a thing when I was a kid. I remember we had a Christmas crib and the three kings were set at a distance and we moved them closer every day until on Twelfth Night they finally arrived at the manger. Perhaps some people still do that. My mother used to insist that the Christmas decorations came down on January 5 because to leave them up any longer was unlucky.
