Yep. Got back from Hamburg at 23:10, got off the train and down in the station in front of the station bookstore there's a horde of people listening intently to some guy tell stories until 0:00 because that's when the Harry Potter sale starts - they even had the food shop next door open specially. On the way home then saw a Harry Potter party at a small corner pub with witch costumes. Weird.
And I've had the 5th book lying around in the corner (the English edition) the whole time and haven't even started reading it...
