Most people view their events and the people they meet through the veil of their own experiences. Wouldn't you agree? It's hard to completely disassociate yourself from your past enough to be a truly blank canvas. But as writers isn't that what we strive for? To present things with no veil, no preconceived notions for the reader to interpret?
I've read books where the author was a little too pushy about how they wanted the reader to read, react and interpret the events of the novel. It was upsetting, as if she was trying to take my agency, my perceptions away. It felt as if she didn't trust me, and overall the experience was a bad one. I didn't like feeling forced or pigeonholed.
I've also read books that presented the most horrible things in such an accepted way that I was disturbed. There are somethings that are not open to interpretation as to whether or not they're good or bad. The fact that the author went to so much trouble to try and make the most reprehensible things seem up for personal choice felt wrong. It made it difficult to trust the author. I didn't know if they would truly support something lke that or if they had done it purely for sensational purposes.
I guess it's a fine line to walk, and the line will vary a bit for everyone, as, once again, our perceptions color how we view things.
And maybe that's what an author owes his readers, honesty.
