What do you think? How do you feel?
I was talking to a friend the other day and we had a pretty in-depth discussion on ambiguity. It ended with me finally sorting out my emotions and thoughts on the matter.
In short: I think it's a good thing.
My reasoning is this: if we are aware, as readers, that events are happening outside the scope of the novel that we're seeing it manipulates our subconscious impressions of these characters. How, you ask? We're being shown that we aren't necessary for these characters to exist. Their existence doesn't depend upon us reading the novel. They are more than what we see.
This, in turn, makes them more real.
(As an aside: way too much ambiguity is bad! Just like anything else in writing, it's a fine line between an author doing this well and completely butchering it.)
How do you feel about ambiguity? Any other tricks you can think of to manipulate* your readers?
*Don't even pretend you don't want to manipulate your readers. You do. You want them to care about your characters.
