"Many years of visiting FR tells me that a serious discussion of this sort of story is impossible."
I was about to leave the thread until I saw your post. I have several reactions to this story, which I shall list below.
1. Isn't it normal in some cultures around the world for parent love making to occur in the same room where the kids are (supposedly) sleeping?
2. What would we do to parents who make love with their bedroom door open?
3. What would we do to parents who didn't take serious steps to make sure their kids weren't listening in?
4. If this made the kid uncomfortable enough to call someone's attention to it, then the parents ought to knock it off.
5. Unless there's some other big problem going on in that home I don't think the mom should do any jail time and the kid should remain with her.
What man here wants a 9 year old girl watching unless he's a pervert?
Not to mention the mother..
I hope the poor little girl's dad has more sense than her mother.
