The Muse Behind Moaning Myrtle
Rowling revealed that the inspiration behind Moaning Myrtle came from “the frequent presence of a crying girl in communal bathrooms, especially at the parties and discos of my youth.
This does not seem to happen in male bathrooms, so I enjoyed placing Harry and Ron in such uncomfortable and unfamiliar territory in Harry Potter and the Chamber of Secrets and Harry Potter and the Half-Blood Prince.”
