I quite like this concept.
So I would give myself an hour to cut a tree and bring in the holly and mistletoe, DD can then be delegated to decorate everything to her hearts content without interference. She'd love that.
Supermarket for a roast dinner, hopefully crackers, champagne and ready rolled pastry for that forgotten jar of last years mincemeat.
Home, suspect I should hoover... get Christmas music on, logs in/light the fire, champagne in the freezer, make mince pies, lay the table with Christmas china and complement DD on her fabulous decorating skills.
Thinking on my feet, grab a bale of sawdust from the barn, tip the chicken food out of a cleanish dust bin and create a lucky dip of presents wrapped in various supermarket bags, Tesco for DH, M and S for mum etc. Lastly created DD's stocking with the contents of her unopened advent calendar.
Turkey scraps for the dogs later on and I wouldn't feel anyone has missed out on much.
