I get you @IrkedEssex
Whilst some people do crave, and need company at Christmas, (because they are quite lonely,) surely a lot of other people can take this opportunity to have a chilled-out Christmas with just their partner/partner and kids? I'm a bit baffled as to why anyone would struggle to just spend time with their partner and children. 
For many people, it will be a relief to not have to drive 100s of miles, or have people at their house 3-4 days or more, causing great stress and extra expense.
No parties, no meals out, seeing hardly any family. Is this really such a bad thing? Save buckets of money, and have less stress. And surely if you have a good, close relationship with your loved ones/parents/adult children etc, you see them fairly frequently during the year anyway? I have never 'got' this desperation to HAVE to spend Christmas day with other people. Nothing wrong with just saying at home alone with your immediate family. Will do a lot of people good IMO, and cause a LOT less stress.
My (adult) kids live 15 and 18 miles away from us (in another borough of the same county,) and we take it in turns to visit each other over the Christmas period. Not always Christmas day, sometimes a few days before.
They were meant to be coming here this year, (on 22nd December,) and hopefully they still can. We see each other fairly regularly during the year, so don't feel a desperate need to see them on Christmas day, although it is nice to see them Christmas day sometimes.
And at the moment, it's looking like we may not see them at all for the rest of this year, let alone for Christmas. (Hope I am wrong!) The best we can hope for is meeting halfway (in a public place, a little tiny market town halfway between us,) on a sunny mid December day, where we can swap gifts. Coz I REALLY don't want to post them all!
However, I would rather not see them til January, and just facetime them, and post the gifts, (or give them to them in January;) and have me and my other half (and everyone else possible) keep our jobs, and as many businesses as possible stay open.
I have heard several people say they don't give a shit what da roolz say, they will see their kids or grandkids anyway/see granny at Christmas anyway, as hell will freeze over before they don't see them Christmas day. 'It's a tradition ya know!' 
It's people like this who are part of the reason for the covid crisis getting so bad. People who think the rules shouldn't apply to them.
And like many others, I enjoy the 3-4 weeks run-up to Christmas more than Christmas day/boxing day anyway.
Someone I know said the 'covid issue' has been a great excuse to not go to Church anymore, as they are bored stiff with it, and dislike some of the parishioners quite a lot. But that's for another discussion!
