Teen DD is a good all round kid so far. Works hard in school, has a good group of friends and from what Ive seen tonight, a strong moral compass. I would say we have rules but not overly conservative or strict. It sounds silly I guess, but she's just told me she's upset as she's found out one of her friends has started vaping. She is upset that her friend has done this in secret at school. I mean, my husband smokes cigarettes so it's not like we've said it's taboo. I was surprised that she was so upset. Fair enough. She thought she should tell a teacher. We've said that it's just her friend acting out. That she shouldn't tell the teacher as what can they really do. Im just not sure what's the right advise to give her. DH said that that's just life and some friends will smoke/drink/ and generally get Up to nonsense but she shouldn't get upset or stop being friends with them. I think that because she's generally a good kid, she's just a bit shocked and upset. I think she's worried for her friend. You read lots of stories on mumsnet so I know this sounds minor, but Im mainly looking for what advise you would give your teen.
