Create New Holiday Traditions
My parents are in their late 60s, my sister and I in our early 30s. We no longer celebrate Christmas at Christmas.
Sounds sad, but it's actually great! My sister and I (who aren't married and don't yet have kids) come home the first week of December and kind of roll Thanksgiving, Christmas and birthdays all into one week. It's much more low key.
Since my parents are retired empty-nesters, they like to spend the winter traveling together...so having an early holiday allows them to be gone at the height of holiday madness...and they don't feel bad about RSVPing no to all those crazy holiday parties! :)
The thing we've learned is that celebrating isn't about a specific day, it's just about being together.
