I happen to not agree that it's "lying" (I'm a fantasy writer, after all), and I believe if we put Jesus first we can still do Santa, etc, as secondary. And technically, my family never did the Easter Bunny because we had three sets of grandparents who bought the kids Easter baskets, so we saw no reason to add a fourth. Plus, despite the fact that both kids believed in Santa (he's a person, albeit magic) and the Tooth Fairy (because fairies *must* exist), they both thought the idea of a giant rabbit leaving colored eggs filled with candy was ludicrous.
This quick post is not to start a debate about any of that though.
What's my point then?
To say this: If you are going to refuse to do these holidays characters do it because it is so STUPID to have to get up in the middle of the night and sneak around.
I was up pulling a tooth for Beastie 2 last night at 2:30 am, because it was bothering her and she couldn't sleep. This meant staying up past 3:00 am to leave her money under the pillow. Which means that this Saturday morning, the Tooth Fairy is TIRED.
