(I was asked for advice, this is not my personal situation)
My friend Jane has a son John who is a freshman in high school. He is going to a school in a new district and meeting all new friends. Jane put some sort of app on his facebook so that she can see all his private messages. She noticed that one of the new friends (boy) is doing alot of talking about getting "head" and having sex. She also put a tracking device on his cell phone so she knows exactly where he is. He has been out skateboarding and tells her he is in one place... but then skateboards all over that area, not staying exactly in that one place (but in the general area).
In the above situation what advice would you give. She didnt call with a specific incident... just the above issues.
