I loved the book. Although i can see other peoples point about not being able to see Sebolds visualization of the afterlife, i disagree. It was very refreshing to read a different view on the topic that i've never heard before. What she was saying was that we all make our own afterlives. Everything we love in the world, not counting people, will be in our own secret haven. Nothing painful, scary or that we disagree with. Only anything you've ever wanted. Even when the people did collide, she knew that they were in their own world, and they knew she was in hers. It was a compromise. They could see eachother, the spirits i mean, without being in eachothers worlds. To me, the private worlds seemed like a human's mind. In person we can see eachother, and intertwine, but no one knows whats going on in eachothers minds. Example: Rowling said that she was walking around all day with people, but in her mind she was at Hogwarts. Thats what it reminded me of anyway. As for the question of why she stayed so long, i have so many answers that i can see as probable, but truly we wouldnt know what we would do, unless we were in that instance.
