I just need to confess: I still celebrate holidays. In fact, I love them. LOVE them. I grew up in a home where holidays were not related to religion. Plus, I knew pretty early on that they were rip-offs of pagan celebrations, which meant to me they up for grabs for anyone, really. Holidays always represented the Four F's: Friends, Family, Food, and Fun. They are bright, happy, sparkle-points of my childhood, and for that reason they remain a part of my life.
So, I continue to celebrate them with my family. We do not bring religion into it. It's more a part of being American and (let's face it) commercially bound.
And while I also recognize that I am a creature of logic and reason, I firmly believe childhood should be a time of magic, wonder, and imagination. Children should be allowed to believe, explore, and delight in the world around them, even if sometimes it's fantastical. We grow up and are faced with reality (responsibility, frailty, ugliness, etc.) soon enough. So, we love the Easter Bunny, Santa Claus, and the Tooth Fairy at my house. One day I will explain to them why I allowed them to believe in certain things while I discouraged a god-belief, and hopefully it's not too hypocritical to make sense to them.
Guess what else? I don't care! Have I mentioned that I LOVE holidays?
