Last year, before our wedding, we felt that we had to appease everyone in our families. Therefore, we spent Thanksgiving day with my family, and Thanksgiving night with his dads family. Christmas we spent with my family...I think, I can't remember.
This year, I said we should do whatever WE want to do and everyone can come to us if they'd like. I want to go to my parents for Thanksgiving, inviting everyone from both his dads side and his moms side (they're divorced, and his dad will been newly married). His dads side probably won't come, so we won't see them.
Which will make Christmas a hassle too. He'll want to see his dads side, since we won't have seen them for Thanksgiving, meanwhile I'd love to go to his moms side for Christmas, as we've never spent that with their side of the family.
