It's not just advertisements, though. In my preacher's sermon today, he was making statements about how we, as Christians, could be controversial with other people of the world, but still portray a Christ-like attitude. He'd make suggestions and ask questions that we knew we weren't supposed to answer, but think about. That's rhetoric!!
I found out that rhetoric is not just in novels and other writings, it's all around me. I even use rhetoric!! I found myself remembering how I had advised someone to go with a Nikon camera instead of a Cannon based merely off of my opinions and thoughts. I'm being rhetorical!!!
