W: I finished the stories about Columbus last time. Now I would like to give you some details about the most truly American national holiday in the United States.
   M: Is it Christmas?
   W: No. Christmas is not a typical American holiday, but the holiday I’m talking here is closely connected with the earliest history of the country and it was first celebrated in 1621 by English settlers.
   M: By English settlers? Why not native Indians?
   W: Well, the settlers, or Pilgrims, fled from their native England to Holland in order to escape the religious prosecution. In 1620, they sailed to America on the Mayflower, seeking a place where they could have freedom of worship. Storms forced them to sail away from their original destination, Jamestown in Virginia.  And after a two-month voyage they landed at Plymouth, Massachusetts, in icy November.
   M: I once read that during the first winter, over half of the settlers died of starvation or epidemics.
   W: True enough. Those who survived began sowing in the first spring. Luckily, a friendly Indian called Squanto taught them how to plant the corn and how to fertilize the soil.
   M: So after the harvests in autumn, did the Pilgrims invite the Indians nearby to a meal for their help and friendship?
   W: Yes, but to be more accurate, a thanksgiving feast.
   M: I see, a day for giving thanks. Then on which day is it celebrated?
   W: At that time, the Pilgrims objected to fixing the celebration by calendar. George Washington, the Public’s first president, set Thursday, November 26, 1789, as the first national Thanksgiving Day. Even so, the controversy continued over the date: Thanksgiving. And since Lincoln’s time, the celebration of Thanksgiving Day has been observed on the fourth Thursday of November until today.
   M: What do we usually do on Thanksgiving Day?
   W: The pattern has never changed through the years. Usually a family journey or a big family dinner is planned for the annual reunion. On the dinner table, you can find apples, oranges, chestnuts, plum puddings, mince pie, squash and so on. And the best and most attractive among them are roast turkey and pumpkin pie.
   M: My mouth is watering now, Mrs. Brown. They have been the most traditional and always my favorite food on Thanksgiving Day. My mum cooks the same as the Americans do that day though we’re not native.
