The letter from Hogwarts arrived in mid-September, a week before her eleventh birthday. Her parents at first thought she’d written it herself, which she guessed was an understandable mistake given how often she’d claimed (and they’d ignored) that one of her "imaginary friends" had written something in her notebooks. Hermione had stopped trying to convince her parents that magic and demons were real some time ago, after they’d taken her to see a psychologist.
