I got home from the theater with my wife and little girl (she’ll be 7 on Tuesday). She came dressed as Hermione, with her robe, wand, etc.
At the start of the movie, when we first see the Dementors flying outside of Hogwarts, my daughter stands up, points her wand at the screen and YELLS, “Expecto Patronum!”
My wife was so embarrassed. I was so proud.
