You can't argue with that logic

"Mommy, lean forward a little bit."
Mommy, who is sitting comfortably on the couch, quite reasonably asks, "Why?"
"So I can hide behind you."
"Oh."
Son puts his face very close to mine, so he can whisper the next part: "But don't keep that in your mind. Because we're playing hide-and-seek, and you need to look allllll over the place everywhere (gesturing widely with arms) to find me."

As the plate comes close to being cleared, Mommy slips one more small piece of pizza onto it. Son looks down at his plate and says with some surprise, "Hey, who put that pizza on my plate?"
"The Pizza Fairy," I say. This standard response typically provokes giggles in our house. Not this night.
"No," says Son sternly. "There are no fairies in town."
"How do you know?"
"I haven't seen ANY fairies lately, and they haven't come by, so I *know* there are no fairies in town."
