The little girl probably caught her parents..or saw some video or something she shouldn't have.

It's so easy to blame society, but kids don't "know" anyone or anything...the best they get is from what their parents teach/show them.

And shame on the lady who wanted to punch a little girl, who most likely didn't know any better. Maybe if you embraced her as a part of your family and gave her a POSITIVE FEMALE ROLE MODEL you wouldn't be catching her in the bathroom. I hope you realize that shame will follow both those kids for the rest of their lives...who knows what that will do to your poor son
