I have an idea for my story and all my characters planned in detail, but I need to expand. It's basically about a young teenage girl and her little brother and sister who are taken away from their parents who have been arrested for using drugs, drinking, having too little income, and abusing the kids. They are sent to a foster home where they are treated poorly (not as bad, but still fairly neglected). I need a conflict for this! It's a simple idea and I need something interesting to happen. I can't decide if I should make it a realistic story, or maybe there's something special about them. I know nobody wants to give me a whole plot, but if you can, please send me an idea! I can't get rid of this writer's block. Thank you!!
