Tradition, family, friends, entertaining, a house full of people for days, happy times, laughter - and a lot of hard work! No, I don't go to church on Christmas Day, but I go to our little country church's Carol Service on the Sunday before Christmas - with mince pies and mulled wine for everyone afterwards. Although our church has a very small congregation throughout the year, practically everyone in the village, and all the children, turn up for Carols before Christmas. It's lovely. I know, for a non-believer, strictly it's hypocritical, but I am prominent in my community so I'm expected to go - and besides - no excuses - I like it, and can trill away with the best of them - as long as no one listens too closely. :o/
(Apart from that, I'm quite a fan of this man Jesus, and feel very sorry for the way he's been treated and misused over the centuries. I'm happy to go to his birthday bash once a year - even if the date is way out).
