Taking my daughter to watch 《Harry Potter》, I can’t help but marvel that Hogwarts School of Witchcraft and Wizardry is probably the least concerned about student safety among the schools I know—things like falling objects from great heights, a hidden room containing a dog, and even snakes in the sewers! And the teaching quality is terrible too. Just look at the birthday cake written by the graduating student-turned-teacher Hagrid—haha.
