I have already finished... but I got it on my trip to scotland when I was in Edinburgh, and I stood near the Edinburgh Castle and saw JKR from a distance and heard her read the part of chapter 6....
it was soo fun... and then I went to buy the book and there were 2 book stores... the one which I was in had a very short line and a deal when you pay the same price HP is everywere and also get 4 more books... and the store next to us had such a long line ( it was midnight 15th of July) the line went out of the store and continued through the whole street...
