Not at all - unless you count panic as part of the christmas spirit. I haven't bought about 90% of the presents I need to get, have no idea what to get anyway, haven't thought about food or who's coming when.... I HAVE written my cards, but haven't got a tree.
I never put up decorations, just a tree, as I hate the empty look of a place when you take the decs down. And I'm not a christian, so the whole thing is a bit hypocritical of me anyway.
I wish I could just hibernate through the entire christmas/new year period, but no-one will let you do that. I can't remember when christmas did not mean worrying about who was going to be upset because I didn't visit them. This year, it will be my parents (like last year!) and boy do I feel guilty about it.
