Imagine if, at the end of the last Harry Potter film, when the credits are done, all the fans started singing: “I don’t wanna see you go but it’s not forever, not forever. Even if it was you know that I would never let it get me down. Cuz you’re the part of me that makes me better wherever I go. And I will try not to cry - cuz there’s no need to say goodbye.” Because every bit of it is true.
