yeah.. those questions are good ones... however, I'm sure i read somewhere the explanation of Rowlings answer to the Petunia and Dumbledore's coorespondence... I'm sure it meant his letter to her when he sent Harry to live with her, and where she replied with a promise to look after him.

I believe that Neville did pull the sword out of the sorting hat as Harry had done in the chamber of secrets... As Dumbledore had said... "Only a true Griffindor could pull the sword out of that hat"...

I'm confused about some of the weird wording in the last chapter, where it was meantioned that someone developed magic late in life.... was that Filch she was talking about???

And i still want to know what Harry chose to do as a career, he spent a lot of time in previous books wondering about that...

Anyways.. I loved the book... I wish it had more information in it... but enjoyed it none the less.
