After spending one Thanksgiving at a sister's house (with quite a group of other single sisters) where she made turkey and stuffing, we all brought side dishes or desserts, and it was just as if we were celebrating the holiday anyhow, I lightened up and started going over to my relatives for dinner on the holidays. Only diff was that we'd leave before presents and I would be careful not to say Happy Thanksgiving/Easter/Christmas to anyone.
My parents started booking dinner at a favorite restaurant (my mother's not up for cooking and enjoys limiting the holiday social time to a couple of hours) for the first sitting...usually around 11:00a.m. on Thanksgiving...so that I could make my bookstudy in the afternoon. I think my parents enjoy the early meal and then going home to do whatever they want for the rest of the day so I'm sure we'll keep to that tradition even after I tell them that I'm no longer a JW.
