Apart from the pleasure of seeing Tom Felton, Devon Murray, Alfred Enoch, Sitara Shah (and waving through the door at Bonnie Wright, who was busy being tutored), I had a great time talking to Dan and Matthew about books, Rupert about how his sisters never wind him up, Oliver and James about how difficult they find it to wind each other up, and Emma about Hermione's love life. Also met, and had a long chat, with Evanna Lynch (Luna), about whom there is only one possible thing to say: perfect.
