Happy birthday, Joanne. I'd just like to say that I wouldn't want to live in world where Harry Potter did not exist, nor you, for that matter.
You and the world you created had been such an inspiration and a big part of my life. There are no words to say how thankful I am, as I'm sure the rest of Potterheads are, of how to thank you for giving us such a great gift. Joanne, you deserve every happiness and blessings you receive.
