I don't know about you, but when I see a white van with no side windows, I'm a bit suspicious. When it also has Harry Potter references*? Well, that's kind of a red flag. So, if you have kids in the 'dorf, remind them not to trust anyone driving the "Hogwarts Express".
* Especially a racist that says "Muggles not wanted". Not just creepy, but also biased against Muggles. Ugh.
