    History of Magic was taught by Professor Binns – a ghost. Harry thought that the subject would have been interesting if it had been taught by anyone else, because the ghost somehow managed to make everything sound less fun than it had any right to be. Still, Harry was learning about magic, so he didn’t dare complain. He sometimes wondered what they would be learning about if they had a proper teacher, especially when Professor Binns completely zoned out during lessons. This happened enough that Harry had noticed Hermione tapping her fingers against her desk, annoyance a furrow in her brow.
