Reading is also becoming acquainted with the characters in the story. The ambiguity of their personality is to an extent synonymous of how the story impacts their life as far as they participate. The more progressed a story is, the more we know about the characters in there. My personal views are that the shorter a story is, the more what we know about the character depends on the consistent story. That's not a law at all, but counts for my scarce experience as a writer so far. Is it easy for you to create a character apart from the world around him/her/it?
