I think Christmas means something different to all of us. Some never get comfortable celebrating it..
Others focus on it being about the birth of Christ
some see is as just a hallmark commercial holiday..
Others see it as a time to decorate and share gifts
and my personal favorite (although I also love to decorate and share gifts) is family getting together..
When I was a JW, I missed out on my dad's family celebrating for so many years. And because of this, I never really felt like I was in my dad's heart as family..
Now my dad was NEVER a JW.. and he doesn't go to any church.. nor I would doubt he prays, but Christmas is HUGE to him.. to the point that 4 yrs ago I wasn't even welcome to come visit him, because I didn't share Christmas with the family (when I was still a dub)...
Personally, whatever reason we choose to celebrate or not celebrate, is not wrong... and finally as NOT brainwashed dubs, we have that choice to make if we want to celebrate or not.
