I meal plan each week, and the Christmas meal plan is carefully done so that once I have done Christmas dinner, the next couple of days are nice and easy, so I can laze on th sofa, watching Christmas TV.
Three years ago, the meal planned for the day after Boxing Day was the left over goose (from the Christmas Day roast), fried in a sticky marinade of honey, soy sauce and five-spice - but when I went to the kitchen to make it, the bowl of left over goose meat was half empty!
After a brief, but intense interrogation, it turned out that ds2 (then aged 19 and a half - so old enough to know better), had had a delicious cold roast goose sandwich for his lunch - and I completely lost the plot!
There were awful snotty tears and lots of wailing about how there was now NOTHING for tea. Ds2 beat a hasty and tactical retreat, whilst dh calmed me down and pointed out that we had plenty of cold gammon and salad left, so we weren't going to starve. He then made tea, whilst I snivelled in the front room.
I actually have pretty much the same meal plan each year - with roast goose for Christmas day, cold roast gammon on Boxing Day and the sticky Asian goose the next day. Each year, since Goose-gate, ds3 has 'joked' about having cold roast goose sandwich - and has withered under my glare!
