I think you could play a very valuable part. I think you could be a postive role model for this girl. Also, you could be in the position where your not going to rat her out, turn her in our hardcore lecture her. You could come from a more easy going perpective that might reach the girl more. Think about how it felt to be 15 and hate authority! Just be honest with her. Treat her like an adult. If she does not listen, do not scold her. Because if you are there for her when she needs you, that is really most valuable. Next time you see her, maybe bring up what you heard. Or maybe only some of it. Don't make it seem like your getting on her case. She will hate it and she might not trust you, Trust is most important. Make sure she knows that she can trust you and knows you are not her parents and although you may not likewhat shes dong, you can't punish her. Once knows wherer you stand she will be more willing to open up to you and listen to you. I hope this all works out!Advice on best friends lil sister...?
Talk to her DO NOT say anything abt all this!! Ask her why she is acting so angry. just say the way u hav acted lately is differert and why?? She could hav been molested or raped or hurt by a boy and no body has understand. let her talk she will say what all she is doing as u say here.
Well i would sit her down and tell her that you know she can do better in life and that you belive in her...Tell her that she has alot of people who care and love her and they are worried about her ....I hope this help's... good luck...
oh my that is not good anyway how about start off nicely and say:';hi Toni!';...';I have heard what u do to ur parents may I know why u do that?';...';If I were you I wouldn't really do that.';...';If you listen to ur parents more then ur friends you will be fine.';...';don't run away from home it will make your parents get worried.';.....well you know I don't know what else you have to say can u just figure out the other stuff about ur conversation?.....but remeber talk slowly,clearly,and nicely....and if she says like a bad word tell her';U shouldn't say that it is rude';..........hope this works n helps.....gud luck
