"Hogwarts is bewitched," said Hermione. "If a Muggle looks at it, all they see is a mouldering old ruin with a sign over the entrance saying DANGER, DO NOT ENTER, UNSAFE."

Yeah, hello Hermione. I know I'm using your name but whatever. Question:

What happens if those kids decide to go and explore? Will they enter the school and see ruins while students see random kids walk in?

What happens if they find a 'weird looking rock' but really it's just a bewitched ball or something? Do they freaking know that it's magical?

J.K Rowling you better answer this because wow there's this door I saw with 'SO NOT ENTER' in Central Park and 'twas open and the stairs lead to this dark alley way...

But my aunt said it was too 'dangerous'. So I didn't go.

ANYWAY!

Please someone answer?
