I once heard tell of a family for whom it was traditional to eat turkey pot pie for their Thanksgiving meal. Some families, I understand, do not serve turkey at all. Some celebrate with extended family, while others observe with only the members of the nuclear unit.
(Our family tradition when I was growing up was for the adults to air their philosophical differences at each other, kind of like Festivus’ The Airing of Grievances. I’ve declined to continue that one. I like to let my resentments smolder.)
That’s the great thing about American holidays: they’re celebrated democratically.
