Encourage the cavewoman to ask her questions

"What do you want to know?" you ask.

She takes a deep breath. "Is everything about this world... this complex?"

"Yes," you tell her. "But you only have to learn about... my cave."

"I can learn that much," she says. "What does that do?"

She's pointing at a light switch. You demonstrate for her.

"That?"

You tell her she doesn't have to worry about your computer.

"That skin on the floor?"

"The rug is so that you can walk on the floor without hurting your feet."

"That's enough for now," she says. She snuggles against you.
