How your characters see things depends greatly upon how you see things. So if you have a parochial point of view, your characters will share that point of view. As writers, we are often told (or convince ourselves) the story writes itself. That’s not always the case. The story may not be written or told if the door to the room in which you want your readers to enter is closed.
Lately, I’ve been practicing with various points of view. Writers are like illusionists, we make our readers see what we want them to see. Let’s say I have a character who is a thief. My readers will see him as a thief. The challenge then becomes what kind of thief they are. What was/is their motivation for becoming a thief? Were they coerced or is it by choice? Are they male, female, or transgendered? Are they white, black, or any derivative in between? Are they Atheist, Christian, Jewish, Muslim, Hindu, Buddhist, or any of a hundred faiths or denominations?
Another factor to consider is the reader. Many readers are open-minded while others are the exact opposite. And everyone brings with them a plethora of life experiences to the table. The POV of your character and how you treat that character will determine how that character will influence the POV of your readers. Which is why I’ve been practicing.
I create one scenario, place my character in it, then I take the same scenario and change my character’s place in it. In one story, they may be the victim of a crime. In another story, they may be the perpetrator. In another, they may be the witness, or family member, or friend, or . . . .
