You know why Christmas is so magical? It's the pageantry. Lights, trees, decorations, songs, cookie icing, family traditions, Santa and the reindeer-- all the events and lore we've made up for a holiday that nowadays has very little to do with a scrunchy little guy in a manger.
For example, today, I asked Dr. Crog to watch the Biscuit while I went to the $1 bins at Target for stocking booty tomorrow. He didn't understand why it was necessary for me to hide these purchases from our astute little dude, and I explained that Santa needs to be more secretive than, "Hey, look at that elephant!" while I drop stickers in the grocery cart. And he wasn't sure we wanted to "do" Santa.
My basic argument was this:
Magical: Santa came down the chimney and put stuff in my stocking!
Non-magical: My mom put some crap in a sock.
See how that works?
Religious or not, creative or not, whoever you are: you've got to admit that Santa is pretty cool.
