Christmas crafting with the youngling:
"Mommy, your reindeer isn't very accurate. Reindeer aren't predators. They're prey so their eyes are on the sides, not in the front."
What I didn't say: "Except for Santa's reindeer. They are carnivores. Hmmm, I wonder what they eat...."
What I actually said: "That's a fine point, kiddo. So the fact that these specimens are red and white striped and one-legged doesn't trouble you?"
"No, I'm using my imagination."
