How come the Muggles don’t hear the bus?” said Harry. “Them!” said Stan contemptuously. “Don’ listen properly, do they? Don’ look properly either. Never notice nuffink, they don’.

No, I'm fine,' said Harry, wondering why he kept telling people this, and wondering whether he had ever been less fine.

How do you remember everything from different books when you are still writing the HP series? As obsessive fans will tell you, I do slip up! Several classrooms move floors mysteriously between books and these are the least serious continuity errors! Most of the fansites will point you in the direction of my mistakes.

Be ruthless about protecting writing days, i.e., do not cave in to endless requests to have "essential" and "long overdue" meetings on those days. The funny thing is that, although writing has been my actual job for several years now, I still seem to have to fight for time in which to do it. Some people do not seem to grasp that I still have to sit down in peace and write the books, apparently believing that they pop up like mushrooms without my connivance. I must therefore guard the time allotted to writing as a Hungarian Horntail guards its firstborn egg.
