We don't do the "presents under the tree" thing. For one thing, our cats would make short work of a tree. We generally buy a few things for the kids (main things -- a Chromebook for one, a new mattress for the other) and each other (I got a sweet ukulele for Tamara, and my main present was the trip to Wisconsin), and give them when they arrive.
To my recollection, a total of one present hasn't arrived yet. I used some cryptocurrency via Purse to order a metal detector. I've been wanting to do that for years, ever since dreaming that I found some pieces of eight in the back yard. Which is actually possible! But I'll be happy to find any metallic evidence of, say, pre-1950s habitation.
We're having dinner with one of the neighbors tomorrow. I've got a standing rib roast and a ham to cook. There will also be mashed potatoes, sweet potatoes (yech -- but the others like them), green beans, etc.
If you're not too busy, share what you're doing for whatever winter holiday (or just winter break) you celebrate.
