It should not have to be that way, and certainly not in the case of thanksgiving.
This Thursday, help keep the “thanks in thanksgiving” by not shopping at a retail store.
You will find few episodes in American history more weather-beaten than the origins of thanksgiving.
1530s, "the giving of thanks," from thanks (n.) + present participle of give (v.). In the specific sense of "public celebration acknowledging divine favors" thanksgiving dates from 1630s (the first one in America was held October 1621 by Plymouth Colony Pilgrims in appreciation of assistance from members of the Massasoit tribe and celebration of the first harvest); though Thanksgiving Day itself is not attested until 1670s.
