(Holy mackerel this is way longer than I expected - you hit a nerve in me!)
Ahh the dreaded social media. Thinking about growing up in Chicago in the days of no SM and the one big thing (the only thing, really) we'd do during Christmas break was visit the mall Santa and then the rest of the time was us in our sweatpants eating sugary cereal. Probably sledding as it was snowy, but no one would know if we did because there were no phones to capture it.
I know that you know this but I'm going to say it anyway - you've no idea what a mood everyone was in before that pic was taken, how much the kids needed coaxing out of the house, the bribery for 'one nice pic'.
I have tickets to one of those 'fancy gardens' to get the kids out in the fresh air tomorrow (Christmas Eve) and we'll take a few nice pictures for relatives back home but if they had it their way they'd play separately in their rooms all day and only talk to us over Alexa (10 and 12, kids not the Alexa).
And I'd clean the kitchen and have a short cry about how they're getting older and when did Christmas go from fun to non-stop chore-a-palooza that starts some time in mid-October, and why do I not get a stocking any more, and oh god did we ever decide if everything gets ripped down before NYE and oh I need to google 'what is twelveth night anyway' and you see where I'm going with this. The Christmas cheer is nowhere near.
So, there's this thing that I do with the teams I work with, we do retrospectives where we look at what went well, what didn't go well, what can we do different next time, etc. And every year on Boxing Day I do one from that Christmas, in the hopes that next Christmas is incrementally better than the last.
So things like 'the pigs in blankets from weren't nice, don't get those again', 'that panettone from was lush, get one of those again', 'don't book in so many things to do, the kids were exhausted and needed a weekend with nothing on, it's OK to not pack every second full of Christmas-ness', stuff like that. And then I put it in my calendar to pop up around mid-October the next year and go 'god I was picky/bossy last year' and ignore half of it.
So I think my one thing on my 2025-Christmas 'be better' list will be 'just enjoy yourself'. Now you've made me cry!
