My Kid, the financial wizard
Yesterday I didn't have any cash, but My Kid did, so I took $20 from his money box before work. When I got home, I said to him, "Oh - I borrowed some money from you."
He said, "I know!" (Apparently he counts his money often.) "It's a loan, so you gotta pay me back more than you took."
Thinking I would give him a little lesson in economics, I asked him, "And what's that called? The extra money I have to pay you back?"
He provided me an economics lesson of his own: "PROFIT."
