Mom and I put the tree up the day after Thanksgiving. My brother wasn't ever interested in helping. And, we send Dad off to do Dad things (golf, woodworking, whatever). And, Mom and I turn on the Christmas music and decorate (and also turn the air conditioning on and put our shorts on - it's always hot out when we decorate for some reason!)
After we're done, Dad comes in and puts a special ornament on the tree. It's in the shape of a white cat that looks like one we used to have that was very special to him. He puts it on (usually putting it into the angel's hand at the top). Stands there and sighs. And, says, "Whew, I had to decorate the Christmas tree again this year."
That's at my parents' home. I don't have one at my home this year (or previous years). I just enjoy theirs when I visit.
I do have garland and lights on my patio this year, though. It's the first year I've had a patio to decorate. Put them up the week before Thanksgiving, because I was going to be out of town shortly after that.
