So you like the tradition of having 12 days of Christmas, and you wish there was a way to get that tradition back, but you don't want to keep the tradition yourself as then you'd be like those sad people who do it for no reason other than tradition. 
I'm not at all jealous of the people who've already taken their decorations down because for me, it's firmly still Christmas. I'm off work, kids are on holiday, decorations are up, we're catching up with one group of friends this afternoon and another tomorrow, we're still enjoying treat food and wine.
It's a little bit less special if I know that some people feel Christmas is over now. That's because as above, one of the special things about Christmas is that everyone is slowing down and celebrating at the same time. I know some people have to or choose to work, I have too previously, but it still makes it special to have a festive atmosphere outside of work.
To be fair most people do at least stop on Christmas Day, and round here the lights and decorations are still all up and I expect will be until at least new year's day, so I'm not majorly fussed what everyone else does.
