Since I hold no judgments against my characters, no matter how heinous they might seem, I present them as real people with their own moral centers. We might feel those moral centers are mis-calibrated, but they are there and are the rudders that propel them. This makes reading my work a visceral roller coaster, 'cause the reader must embark on the journey of the protagonist equipped only with his or her own moral center.
I read everywhere. It's like a bodily function. I don't need quiet. I write and read with the TV on. I follow the TV show while I read. TV doesn't require a lot of brainpower.
