A grown-up sent you to the shop with money for a specific thing and told you to bring back the change. You felt trusted — properly trusted, like someone who could be relied on. At the shop, you got the thing. But there, right by the till, was something you really wanted, and the change in your hand would cover it exactly. The grown-up didn't say exactly how much change there should be. They might not even check. You could buy the thing you want, come back with no change, and just say it cost a bit more than expected. Nobody would probably ever know. The only thing standing between you and the thing you want is whether being trusted actually means something to you when no one's watching.
