Friend abused by sibling?

that is really sad. omg i cant even imagine how upset i would be! i think you should just keep on encouraging katie to go to a counseler at your school. really try to get her to go! i wouldn't call the police though because even though annie did that stuff i think katie might be kind of mad at u for putting her sister in juvie. and you might get to involved in it and thats something you dont want to do. so avoid doing that. also, talk to YOUR parents about it and have them call katie's parents. anyway i really hope you get this solved! :)
