I come from a family of foodies. And geeks. On the subject of food: We had two turkeys and a ham this year for Christmas Eve dinner (rosemary roast turkey and Cajun fried turkey). For 10 people. And then followed that up with a slow-roasted prime rib for lunch on Christmas Day. On the subject of geekdom: Ever since we can remember, my brother and I have been watching Star Trek, and my dad introduced me to Asimov while I was still in elementary school. Even my relatively normal mom, who never seems terribly nerdy, watched Babylon 5 from the beginning while it was airing on network TV - we all thought the show was silly (the makeup and special effects were less than stellar) and would poke fun at her for watching it, but when the series started to pick up steam somewhere in the second season it was my mother who had the last laugh. We all became fans, and Babylon 5 is still one of my favorite science fiction TV shows of all time.
Over the last couple of years, Christmas presents in my family have tended toward cooking-related items, and this year continued the trend. Combining the food and the geek themes, my brother and his wife bought me a set of Star Wars cookie cutters and pancake molds. They're pretty awesome.
All that to say, I hope all of you have been able to spend time with the people (nerdy or otherwise) that you care about this holiday season. Merry Christmas!
