A Wizard in a Muggle world

McGonagall tells Draco that they are sending a few students into the muggle world to learn more about it, and that he was one of the chosen. He has to go school. One Problem. He doesn't know anything. Nothing about algebraic questions, tricolons, or what the difference is between acids and alkalis. Hogwarts was great for charms and all that, and how to kill death eaters, but not for learning to play sports without flying brooms. All he has to help him is one book, which contains everything about the muggle world. Great! You must be thinking. Problem solved! Yeah, apart from one tiny detail. The book was written two hundred years ago. A lot has changed since then. When you think about it, muggles, on the outside, they're a lot like wizards and witches. Even though, the majority of them try to fit the word, 'like' into their sentences every five seconds. But they certainly do act very differently. And some of the things they talk about! How on earth are you supposed to know what they are? Toasters? Snapchat? The Clash? How even is this Justin Beaver guy, and why does everyone love him? This is far to confusing for him...
