I get what you are saying, and I agree with you. AND I am completely guilty of this, I have been a total Scrooge this year. I am so glad the holidays are over. Your post got me thinking about why that is though - I hadn't really sat down and "soul searched" as to why this is... normally I LOVE the holidays... here's what I have come up with.
First. Money. We built a new house last year, and this is our first holiday in it. I LOVE

my new house, but moving into it raised my monthly bills by about $400 a month. We make it, but just barely. Everytime I bought something for the holiday, it was always foremost in my mind how that money could be put to better use. I got laid off from my part-time job 3 days before Christmas too (yeah, Merry Freaking Christmas, here's your pink slip..), so that really didn't help either.
Second. Weather. The older I get the more I HATE winter. Sometimes I think I have that Seasonal Depression thing. I hate snow and cold and winter so badly, all I want is for it to be spring again, and in order for that to happen, Christmas needs to be GONE.
Third. Family gatherings. I wouldn't say this to anyone but my Dis friends, but I truely detest most of my husband's family. We have been married 16 years, and I really have tried to like them, but I just give up. I don't. I can't. I can avoid them, or limit my time with them most of the year, but that doesn't fly at the holidays. My mom and the rest of my family don't live nearby anymore, so in between missing my family terribly and having to be with THEM so much, I just dread the holiday season. I spent Christmas Eve, Christmas afternoon, and Sunday afternoon with the inlaws.

If the holidays are done, I can go back to avoiding them again.
Fourth. Expectations. Everyone "expects" thing from you this time of year. You must shop. You must hang out with the extended family. You must spend too much on gifts. You must enjoy holiday music. You must believe in the "true" meaning or somehow you are just plain WRONG.
You know, you never see someone post on how stressed they are and how much they hate the holiday at Halloween. Or Fourth of July. Or Memorial Day. I think those holidays just have so fewer expectations. So fewer "you must do this or it just isn't Christmas" stresses.
I think I am just tired of the stress and the expectations.
I told Dh that next year I want to go somewhere "preferably warm" and rent a condo or a cabin. No one but us and the kids. no freinds, no relatives, no shopping, no cleaning up, no "it just isn't Christmas without the TURKEY!". just us, a beach, some presents, and Blessed silence.
