And it really shouldn't.
Because according to the rules of decorating for Christmas, it shouldn't officially begin until noon on Thanksgiving day. I'm pretty sure that's the earliest that you could technically put up the lights, the tree and everything else.
At my parents house, we don't put up the lights, garlands and tree until the day after Thanksgiving. On that glorious Friday, we all wake up early (meaning my sister drags us out of bed)and hit the shops at 6 in the morning. After that we decorate the tree and generally argue on what to do with the garland. We argue about it every year so I guess it's pretty much tradition now.
Anyways, back to my point. We shouldn't be decorating for Christmas...yet.
