"Unsure Aunt" should also be prepared to lose her sister over this.

That doesn't mean she shouldn't intervene, though.

Um...yes it does. She has no right to take her sister's child from her.

What gall to assume you can just swoop in and take someone's kids away. Most parent/child relationships are turbulent to some extent in the teen years. You don't just take someone's kids away because YOU don't agree with their lifestyle choices. If this beeyotch really wanted to help her sister, she would get her a$$ over to her house and babysit in the evening and try wield some positive influence in a less destructive way than breaking up a family.

I have a strong feeling this self righteous poser doesn't really want to help her sister----she wants to show her up so she can look like the hero/savior.

I just meant that fear of losing one's relationship with a relative shouldn't keep one from intervening if one believes the children are in real danger.
