There's been a lot of discussion about whether J.K. Rowling should reveal the professions/sexual orientations/favorite colors of her characters if she didn't write about in the published books.
But, let's say for a moment that she didn't and that there was no further information about Harry and friends other than what was contained in the pages of the seven novels.
What do you think the future of the characters are? What would you like them to be? Without straying too far into the area of fan fiction... what careers/relationships/pets/whatever would you imagine they have?
Although this discussion question doesn't really contain spoilers (even if you haven't read the 7th book, you probably assume that at least a character or two survived until the end)... my guess is that the comments section will be full of spoilers- so be careful if you haven't finished the book.
For more discussion questions about Book 7, see this post. Also, check out this post for some bonus discussion questions that were actually asked to (and answered by) J.K. Rowling.
UPDATE: Yes, there are spoilers in the comments section of this post. For my opinion(s) about the future of the characters (with huge spoilers)... see here.
