With such warm weather in November, if you don't have your outside Christmas decorations up yet, this might be a good time to do it.
Some times these things can become a competition or an attempt to out do your neighbor and the whole "spirit of Christmas" can be lost.
In the picture below, notice how the guy in the house on the right was able to decorate his house tastefully even though the person on the left was a little ostentatious.
If you make your own Christmas cards, you might want to use this picture this year.
