My sister will be working Christmas day, like she does every year, and will be fighting with her husband, as she does every year - my mum and stepdad will be going away, my dad will be home in Russia and Steve doesn't talk to anyone in his family apart from his aunt and cousin so we manage to escape all the noise and fuss other people get.
It's not so bad if you're at someone else's house but when you're entertaining it's too much...both Steve and I are fairly antisocial creatures so a quiet day in will suit us just fine
