I think the younger generation enjoy family Christmases very much, but have very little intention of taking up the baton, because 'we work, you know.' Our generation, obviously , never did.
When I worked, my younger colleagues were appalled by the idea that they should even consider hosting Christmas, and I am watching young families loading up cars now where I live, having spent Christmas with mum and dad.
Again.
On the other hand, I have two friends who won't allow their daughters to cook; one insists that the family, ( 4 adults one child plus large dog) comes to stay in her two bedroomed house, then complains no one helps her, and the other one cooks the entire meal and takes it up to her daughter's house for her family on Christmas day.
Me? After 40 years of hosting I have had Christmas Day at my daughter and partner's house for the first time ever, and it was WONDERFUL.
