Cause and Effect

I am reading Nobody's There by Joan Lowery Nixon. In my book there is a girl named Abbie she sees her dad breaking up with her soon to be step mom and Abbie gets so mad she throws rocks though her dads ex girlfriends house. When Abbie did this her dads ex girlfriends roommate called the police. Abbie now has to spend most of her day's with a old lady. The old lady is really mean. Abbie has to drive the old lady everywhere.
