There's nothing better in a conversation with a child than asking them about something they know. So, the boy started talking about the process of making paper, how a printing press works, and even though he didn't really know half of the things he was saying, he still managed to come up with some interesting ideas. For example, in his version, paper becomes white because it's rubbed with the wings of cabbage white butterflies.
The hours flew by as he talked, and the boy was already talking about newspapers, and then about what gunpowder is made of ("What, you don't know? It's made from bird droppings! They take it, dry it, rub it in their hands, and put it in special bags!"), and how a goblin, probably Udi-Lar, entered the house.
--Who are you talking to?
