I am seeking advice from parents with teenagers or someone with experience with teenagers. My sister is 14 years old and recently this year has been hanging out with the wrong people. She has been skipping class, lieing a lot, drinking, smoking, and possibly doing drugs. Although I don't have proof, she has recently reeked of cigars and possibly cigarettes, I confronted her about it and claims she was hanging out with people smoking. I could be wrong though. Her marks in school have been dropping and she doesn't listen to my mom at all anymore. Even with small things like emptying the dishwasher or walking the dog. I know that if my dad was here she would listen. But she just seems to ignore everything mom says. She denies everything she does wrong and lies more then usual. Anything you guys can advice my mom does? She just doesn't know what to do anymore... Please PM me or post help here.
