I would have two thanksgivings, but I decided not to go to one, today, with some of my stepfamily.
The people aren't mean, the food is good, but frankly I have nothing in common with them.
I really don't belong there.
The second one will be with my family and I look forward to it.
As for the holiday, I don't think of it's origins, the same as I do not for christmas. Neither origin I respect, they are to me a time for family gatherings and such.
