All power to your elbow, winterwhite! If it's my turn to host Christmas Day, as it is this year, I'm up to my elbows in preparation for that on Christmas Eve, with DH assisting where required! I usually down tools at teatime, have a quick bite, and get ready to head out for a festive few drinks with him and whoever else is around to join us, ending up at the midnight service on the way home.
I'm impressed that you sort out a Christmas Eve supper at home for everyone if you're feeding them on Christmas Day. And I certainly couldn't do with them all getting under my feet in the kitchen. If nobody else is willing or able to do the work, I'd be booking a table for everyone at a local pub!
