10 Things That Would Worry You If The Harry Potter World Was Real

8. That Pesky Marauder€™s Map

So the twins saw Ron snoozing with someone named Peter Pettigrew every night and didn't raise any concern about it? Perhaps they felt that their brother had some lover locked up in his closet (which he hid very well under a Concealment Charm, of course) and decided to let him be. Whatever their reason, it still doesn't hide the fact that the Marauder's Map is one frightening tool when left in the wrong hands. In Harry Potter And The Prisoner Of Azkaban, Remus Lupin discovers that Peter Pettigrew is alive (after he was pronounced dead 12 years before) in turn realising that Sirius Black was innocent. And in The Deathly Hallows, Harry uses the map to track Draco Malfoy down, as he was sure that Malfoy was doing dirty work for Lord Voldemort. Both good causes, but if it wasn't a good guy using it then things would be pretty dangerous. Imagine if the government had something like a Marauder's Map to keep tabs on you. They would know exactly where you were and at what time. Actually, that's pretty much Facebook.
