There is a very old Art Buchwald column in which he explains Thanksgiving to the French. I have fond memories of reading it each year in the International Herald Tribune when I lived in France, several decades ago. You can read the whole thing here, but near the end he concludes:
And so, on the fourth Thursday in November, American families sit down at a large table brimming with tasty dishes and, for the only time during the year, eat better than the French do.
If you are celebrating today, I hope that will be true for you. Bon appetite!
