I think when you care enough or Love someone that you will go out of your way to correct them, to try and bring reason to them, even stop them from making a mistake when they are entering a dark area that offers no help for them and they will be alone when something happens. Especially a child or teen. There are Christians in the world who are putting their lives in danger just trying to help, correct, and Teach the Wisdom of Jesus. For you know once that if she finds enjoyment in those dark places, she will be like a dog returning to its vomit or a fool repeats his folly.
Perhaps going over some of the dangers with her may help her make a wiser choice. Yet, if she says she wants to have fun, that this is fun, fun this or fun that, then all you can do is tell her parents or call the police and say where the party is or if you wish, just let her go and if she dies then she chose her fate. If she gets HIV/AIDS, she chose her fate. If she kills another while driving, she chose her path. IF she dies from a drug overdose, she chose her fate. How much do you really care for her that you will do what it takes to keep her safe? If we care enough about someone, we will do what we can to help them and correct them. If we didn't care, we would do nothing and let them face their fate. If I have the power to do something, I always do, even if they hate me for correcting them or they hate me for stopping them. At least I did what was right, because I cared. God Bless.
