You are so correct. My friend's daughter (age 14) has always been interested in boys. So, the family has supervised her well and made sure to surround her with good role models. They got her involved in their active parish's youth group and now she's working with that group 3 nights weekly plus on Sundays. The group is so active that it puts of religious plays and musicals all over the state (with the parents along for the ride). We had the girl over two months ago and couldn't believe the difference...she talks about her high grades, her church friends (mostly girls), her drama and singing activities and everything BUT boys. They are far down on her list right now and it's great to see.
It's up to PARENTS to guide their children plus supervise them. Too often we want to be friends and be popular with our children. That's not what parents were put on this earth to be!
