My mother always said it was "tacky" to put up Christmas decorations before Thanksgiving was over, so I always wait. (my mother also told me how "tacky" I was, for leaving my decorations up until April one year, lol)

Not that I necessarily agree with her on the issue, I see many people with them up already, but even if I wanted to, I haven't had the time yet. Will try to get it done before the 1st week of Dec.
