In the past I called Christmas time hiking time. The family couldn't decide which traditions to celebrate, which resulted in each doing their own thing. They expected me to be there nevertheless so I walked around the city until I was finally at home around 11 pm Christmas Eve.
Now we celebrate together, this year it's my turn. As we are the odd mix religion-wise we just do what we/the host likes. Which usually is Christmas Tree, dinner with the family and presents on Christmas Eve. When I'm the host this means vegetarian dinner of course, *snicker* Well I would cook meat/fish/birdies if someone couldn't live without, but so far everyone was okay with it as long as I made feta cheese pizza, fresh bread and tiramisu among other things.
We play music, traditional and not so traditional christmas songs. Then there are the presents, mostly for the kids, after this the family members who want to go to Christmas Mass do that.
Next year I'll dig a den somewhere outside the city and have my private Christmas. I need this once in a while.
