Thanksgiving deals with the Pilgrims introduction to the new world. It was supposed to be a big feast between the Pilgrims and Native Americans. It's mostly used today to represent what we as Americans should be thankful for.
The purpose of Thanksgiving dinner is to gather as family and friends and reflect on your many blessings. We have the tradition of going around the table and each person recounts their most important blessings of the year. It is a time to enjoy the bounty that the group has enjoyed throughout the year.
