Still waiting for either of you to provide a link to a law that says a 17 year old no longer has to follow his parents' directives.
I don't know who you're referring to as "either of you", but if you're referring to me, I never said a 17 year old doesn't have to follow parents' directives.
My only position in this matter is the statement that the information I found says that a parent can't get a RO in OK unless there is danger to the child. And holding hands would not be danger to the child if that's all that happened.
The parents could still tell the kid to stay away - and could punish/take away privileges all they want, but I don't see that they could get an RO (unless there's a different statute that I missed).
There is also the possibility that some criminal charges could be made - such as corruption of a minor, but I'm having a hard time believing that a prosecutor would ever take the case of a 19 year old and 17 year old holding hands (again, unless they were doing more than that).
