Every family has its own Christmas traditions, particularly the British royal family, as Meghan Markle is soon to find out by spending her first festive season with the Queen and co.
While the chances of an early morning piss-up at the pub by a roasting hot fire seem unlikely, as does the inevitable argument when someone burns the turkey, Prince Harry's new fiancée Meghan will already be changing how the royals do things.
This is because Meghan will break long-standing royal tradition by being the first royal fiancée to spend Christmas Day with the Harry's family. Even Princess Diana didn't get that... Perhaps not that surprising, really.
"Now they are engaged it was unthinkable that they would be apart for Christmas," a friend of Prince Harry's said, according to The Times. "The royal family have fully welcomed Meghan into the fold."
This really is an exception to the long-standing royal rule, as even in 2010 when Prince William and Kate Middleton got engaged, they spent Christmas apart.
Catherine of Sussex - Kate's official title now - instead had a nice traditional Christmas with her family in Berkshire. I would have been gutted, to be honest.
The reason for the U-turn is because, apparently, Prince Harry asked the Queen to make an exception for his new American bride-to-be.
According to Vanity Fair, Harry was typically upbeat when it came to discussing the special treatment that Markle has received, both from his famous grandma the Queen and from her beloved corgis.
"I've spent the last 33 years being barked at - this one walks in, absolutely nothing!" he said in the pair's first joint interview together. You know that once your in-laws' dogs like you, you've made a good impression.
Meghan may be shocked by a few of the royals' traditions, though. Instead of a relaxing day with family, she'll have to get used to a black-tie dinner, a full English breakfast, and the weirdness of watching your grandmother-in-law deliver a speech to the entire country. Just your casual Christmas Day.
Even worse for Meghan, on Boxing Day it's tradition for the Harry's family to go and shoot pheasants on the 20,000 acre royal grounds. She's opposed to blood sports, so I can't imagine that she'll be up for that.
Hopefully the royals won't take Meghan's snub too seriously if she doesn't fancy spending her festive season killing a few unsuspecting birds. I guess that her presence will take some getting used to.
