She really has created a fantasy world out of Hogwarts and Potter. The characters have taken a life of their own that people seemed to think of them as next-door neighbors. I just know that we'll all be saddened once the series comes to an end. It has gone beyond the I-like-this-book-it's-great to I-love-this-book-it's-an-absolute-favorite.
While the most recent book has a sad ending with one of the major characters dying, it just left the readers desperate for the next, and it was said, last installment. While it would be great to have that, it would mean a doleful goodbye to something that has become an immensely enjoyable pastime in our lives.
Sure, we can go back to reading it again and again. But, it would be different. In our minds, Harry, Ron and Hermione will go on living but it won't be with us.
Harry Potter is not just enjoyable reading, it has become our playground where we are again, a child, wide-eyed and able to believe in the wonders both known and unknown to us. It' s a very nice feeling. And, one that would be most difficult to part with.
