@Smileyrius,
The experience of not believing in Santa can be problematic when surrounded with kids, many of whom believe in Him. Happened to me recently. My kids are older, I forgot. I asked my nieces if they liked the princess dresses we sent them for xmas, and the oldest retorted: "Tu veux dire, les robes du Pere Noel?" (you mean, Santa's dresses?)
What I would like to know is why do we all, even the hard-core atheists among us, teach our kids to believe in this totally goofy myth of Santa Claus? Is it social pressure? Is it because, for about 3 months a year, you can better control your kids' behavior with the threat of no gifts for xmas? Is it just because it is cute? What does that say about humanity's need to enchant, to mythologize life?
