Since seven o’clock in the morning, the Madisons had been up and busy around. It was no simple matter to prepare a feast from soup to nuts. Still, Mrs Madison would not change places for anything or anybody. She enjoyed days such as this when all the family- aunts, uncles, cousins, grandparents- came for a visit, each bringing a contribution to the overall festivities. The Madisons, themselves, supplied the turkey. One more Thanksgiving Day. This was a sentimental holiday. It was a suitable time for cozy family reunions. Aside from the origins of the day, extending back to the time of the original settlers, the occasion also reminded the Madisons of the fact that they had to be thankful for living in a country such as the United States.
