Imagine two children learning about ancient Rome.
Child one reads a chapter.
A photograph of the Colosseum. A date. A paragraph about gladiators. Three vocabulary words for Friday's quiz. She reads it under fluorescent light, scores well, and forgets nearly all of it within a month. The knowledge never had anything to hold onto.
Child two stands inside it.
She feels the heat of the stone through her shoes. She hears her voice echo where fifty thousand once roared. Her father asks one question, and something clicks into place that will never come loose.
"How do you think they got everyone in and out so fast?"
