AFAIK Thanksgiving is not really celebrated outside North America (and IIRC Canadians have it on a different date). Not because we would not have many things to be thankful about, but simply because the tradition does not exist. Anyway, those of us furriners who have seen "Planes, trains and automobiles" have gotten a glimpse of how much it means to those who do follow this tradition.
So, enjoy your Thanksgiving. With your loved ones, if at all possible.
