So what would y'all do if your 13 year old sister told you have she has messed around with a 18 year old guy that she is still seeing and has smoked weed?? Our parents are clueless about it. They have pulled her away from the friend that is the problem but is stil sneaking around with her and the guy. I know she is a teen but I'm worried about her! She now trust me to tell me things that she is doing idk if I should keep that trust in case something does happen she has someone to trush and tell or should I tell my parents!? I'm stuck!! Now being 24 I know know how I was as a teen and know the consequences I got from my parents. I need some opinions.
