The annual family pantomime (as traditional and saucy as can be)
The smell of the Christmas tree - and the baubles collected over the years from holidays, or made by the kids
Carols in our local car park - with an orchestra, father Christmas, and choir on Christmas eve
Getting together with the family, opening presents, eating and playing games
Christmas movies on the TV 24/7
Roast potatoes, pigs in blankets, Brussel sprouts and mince pies (not all at once)
Expandable waistbands and pjs that can be pulled on as soon as it gets dark
