I hate waiting, I also hate suspense, most books make you wait suspensefully for the ending. If I'm really into a character, I want to know what happens to them. Spoilers for the rest of the paragraph. I don't like it when my favorite character commits suicide (The Sound and the Fury), dies unexpectantly and for no reason (Message in a Bottle) or ends up being the bad guy, I mean the really bad guy, not the bad guy that you love to hate (American Psycho), but the "OMG! you're the killer, really!?" bad guy (In the Cut).
