My son has his own jobs at Christmas. He likes making a chocolate house cake, helping me ice the Christmas Cake. He now makes the cake himself (he’s strong and 39) I have arthritis in my hands. He likes to be in charge of what decorations go where.
He also takes charge of filling up the firewood basket, bringing wood up from the bottom of the garden - good exercise. Also have a quiet time planned, for jig saw puzzles, watching a favourite Christmas special.
I always sort out nice food for everyone, according to my son we live on “scraps” for the days after December 25th. Cold meats, cheeses, salads, cakes, trifle, cheesecake!
