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.
