Definitions of the word "pilgrim":
From Wikipedia: A pilgrim (from the Latin peregrinus) is a traveler (literally one who has come from afar) who is on a journey to a holy place.
In American history: The legendary, mostly mythical story of the Pilgrims in Massachusetts, who came from England for religious freedom. They did okay, except for the large percentage of them who died those first few years, and they shared that first Thanksgiving dinner with the native Americans, who had, willingly or not, shared their vast lands.
Today, Thanksgiving 2012: Those who gobble down their Thanksgiving dinner to rush to be first in line when the stores open on Black Friday.... and now, to their shame and to the abuse of their employees, some of those stores are even opening on Thanksgiving evening.
