Just a couple days ago me and my brother caught my little fifteen year old sister doing something she shouldn't be doing, smoking. She was smoking in her room with her friend and obviously the smell made it obvious. My mom wasn't home and me and my brother weren't sure of what to do. We talked about it and we made the decision to not tell my mom and have a talk with her. We let her know we weren't going to stop her because it was her body her decision, we simply let her know of the consequences. We explained to her what she was doing could cause and the troubles she could get herself in. We told her we weren't going to get her in trouble with mom, because she had been very distant from everyone in the family since my dad passed away last year. The last thing we want to do is push her away more by having her dislike us. We feel like we did the right thing because she will trust us to talk to us no matter what she does good or bad. Teenagers are curious and I feel she was curious, think we did the right thing?
