Fictional Friends

I just read an interesting article titled "Bad Book Review Sparks Fictional Friendship."  When writing his novel, The Bright River, Patrick Somerville decided to open an email account for one of his characters, and the character actually received real email (not just spam).  A reader was confused about something in the story and decided to ask the person they thought would know best--the character in question.  A friendship of sorts ensued.  This started me thinking about questions I would ask book characters if I were able.  I have many questions for Mrs. Rochester in Jane Eyre, and for both Rose and Joseph in the Particular Sadness of Lemon Cake by Aimee Bender.  Who would you have questions for?
