Okay, kiddo, imagine someone is playing a big game where they promise to help everyone and follow the rules. The people watching the game—the ones who gave them their job—start asking questions, like, "Are you really playing fair?" If the players don’t answer, the people might think they’re hiding something.
Now, if those players were just regular people, we could say, “That’s private, don’t worry about it.” But they’re not—everyone helped pick them, everyone pays them, and they even sell stories about themselves. So it is people’s business to ask.
And if everything—like doctor's notes or family records—was already out there for everyone to see, people wouldn’t need to ask. But it’s not, so they do.
I feel like I am talking to a five year old.
