How much Christmas is just for me?

I mused aloud to my family as to whether we ought to get a real tree this year or whether we should pull out the fake one we have, as I love real ones but they are a bit of a pain to fetch home, trim and then water every day. 
Their response? *shrug*
"Don't you have an opinion about Christmas trees? Any preference at all?"
No, they didn't.  None of them cared.  I already knew none of them seemed too interested in decorating the tree, I usually had to bribe / wheedle help, but to find they didn't care if we had one?  I was a bit surprised and even in denial about it.

This afternoon I asked a few questions of 'they guys'... they don't care about gingerbread or want it, they don't care about popcorn balls or have any interest in decorating.  My hubby still likes twinkle lights at least, but apparently more because the neighbors see them than for us. Still need to interview the daughter to see if I have anyone who will share Christmas with me in my own house, she's been generous in allowing me to steer her into threading popcorn as we watch a holiday show in the past, for instance, but now I wonder if she even likes it.  Or are they all just humouring me?

I'm a bit taken aback at the moment, will need to process this.  How much of my Christmas activity is just, it seems, for me only rather than (as I imagined) shared positive times -  And if so, how much of it will I still pursue?  I'll have to ponder.
