SWMBO is putting them up as I type this.
I expect to be called to assist with removing the tree from under the spare bed in the next 30 minutes or so, I'm hoping the outside decorations are postponed until next weekend, it's dark and cold out and I'm pleasantly toasty and half cut on ginger wine inside :)
They will be taken down the first Thursday after new year as that's SWMBO's day off and she knows I'm not a fan of any of this.
Most of the time I have spent living away from my parents I've ignored the festivities, and when I married my wife 5 years ago (having lived alone for close to 20 years) the only christmas stuff I had was a 6" tree and some tinsel left over from a vicitm of a drunken hen night many years before I met the missus.
