I couldn't cope with that - I need to have a plan in place and know that I have the main constituents of that plan here, otherwise my stress levels get too high, and that impacts my mental health.
I suspect I am your polar opposite - by the beginning of the week, I had made and frozen braised red cabbage, apple sauce, bread crumbs, stock and peeled chestnuts. The goose for tomorrow and the gammon for Boxing Day were in the freezer too, and I had a Tesco delivery booked for Wednesday, that I booked as soon as the slots were available.
Worse than that, I have a set of lists, on the computer, of all the things that need doing in the run-up to Christmas - usually this is in a note book, but this year I put it on the computer, to save me work next year (sad, yes), and have been working through that methodically, to make sure I was well ahead of what needed doing.
Dh went to the supermarket at the crack of dawn, to get fresh bread, and one or two other bits and pieces he decided we need, but I'd rather not have to set foot in a supermarket today, if at all possible (though they don't seem to get so manic round here).
I'm having a rest at the moment, having hacked through a large proportion of my Christmas Eve list - prepping veg, making stuffing, bread sauce, gravy, brandy butter, boiling and glazing the gammon, stuffing the goose, and baking some gingerbread biscuits and parmesan shortbreads (I made and chilled the doughs yesterday).
