that is always tuff......the bad thing is that you can't force someone to change....it will have to come with growing up and time. Some people have to have something major happen and hit rock bottome before they decide to do anything.
Girl, I was so bad growing up my mom hadn't a clue what to do with me. I did drugs, ran away, got arrested twice, stole the family car....Yeah, me and you see how I've turned out. My dad even put me in a crazy people home because he was at his wits end with me and that didn't even do it.
