This will be our 14th Christmas abroad, and our 12th without any family here, so it's fairly normal for us. In a way it's nice to be away from all the expectations, and just do our own thing. We don't get caught up in the madness of driving long distances, crazy amounts of groceries, big supermarket queues, etc. We do go out and buy some nice stuff but not silly amounts.
We decorate a bit - we get a tree and hang lots on it, and put lights up in the garden. In my town, people do a really nice job of decorating their front gardens.
Fairly early on in the season I track down things like glace cherries, mixed fruit, mince pie filling etc - they're not easy to find but not impossible.
We have a Christmas Day routine. Nice brunch, then presents, then a walk around the town and watch people skating on the pond, then home to cook a nice piece of beef, gravy, etc. Crackers at the table, and silly hats.
It usually snows here before Christmas, so that makes it feel 'proper'.
I don't miss Christmas in the UK, I just miss my family like crazy. I haven't seen them since 2019, and I really had hoped to see them at some point in 2020.
