Grown-up stone

"I want to have a sleep-over at Sheila's. She has a magic stone that has special-er magic than my black stone." We were driving to Quaker meeting, and Genevieve had a captive audience.

"What does it do?" I asked.

"It only works for children. If a grown-up comes in, they would get poisoned, and I don't want you to get poisoned."

"So if you were there using it, you wouldn't want a grown-up to come in because it could poison them"

"Mmm-hmm."

"Well, that's very considerate of you." Good to know she's looking out for me. "So what kind of magic does it do?"

"Sheila didn't tell me yet, but I think I heard her say that it makes smoke to try to kill the grown-up, so that when the grown-up comes in, you forget where you're going and get lost, and it hates grown-ups."

"What does it do without grown-ups around?"

"Oh, well, the princess turns into an evil queen, and she has magic that makes you get lost, and ..."

...and on it goes with castles and rescues and danger, all rendered in spoken phrases not capable of being logically linked by a grown-up, but I'll bet that Reesa understood every word her sister said.
