I go to work one or two days a week and that's plenty of being sociable for me - definitely don't need more! There are a few friends that make me want more, since work people are definitely colleagues, not actual friends, but still I have limits.

I'm glad you had Christmas Day with some good people, even if it did get to be a bit too much. It's one thing to be with your friend, another for sure to have to deal with all his family.
