Each of my kids gets "one want, one need, one wear, one read" for Christmas. I shop for nieces and nephews, an elderly aunt, my grandmother, and DH's parents. DH's parents go crazy for Christmas. I've asked them to tone it down, but they just enjoy buying things I think.
I grew up without Christmas due to may parent's religion (so no Christmas gifts to buy on that side), but they did allow us to make gingerbread houses at the holiday times with our cousins. I think most of Christmas is over-the-top crazy.
My tradition is Gingerbread House Party which I've been doing for the past 13 years with friends/kids. This year, we're throwing the party for my daughter's Girl Scout troop. It is likely the last year of the large parties, as she'll be in middle school next year and I've discovered MMM. It will be 23 gingerbread houses, with the party costing roughly $200....BUT I will take a tax deduction for the donation to Girl Scouts. There are girls of all different religions in her girl scout troop, and everyone can participate since it isn't religious.
I'd like to stop doing the holiday cards since I see everyone on Facebook often enough, but DH would have a fit....
