I'm one of the people who excitedly decorates for Christmas a week or so before Thanksgiving. In early November, I start planning for Christmas, shopping for Christmas, and getting very excited for Christmas!
This doesn't mean that we aren't celebrating Thanksgiving. It simply means that I see the next two months as HOLIDAY TIME!! I go into FULL holiday mode!! I love it all and in some ways, I feel that Thanksgiving and Christmas kind of go together all as one holiday. How perfect!
