NC for this.
If you were aware of a household where there were frequent alcohol fuelled arguments between a mother and her teenage daughter, including physical aggression (think punching walls/doors), and there was also a 4 year old child in the home witnessing a lot of this, who you're told has developed a tendency to become aggressive themselves... What would you do? Would you make an anonymous report? Or stay out of it?
This is not family or even a friend. More an acquaintance. I haven't personally witnessed this first hand myself, it's been reported to me by a third party who has witnessed it, and is definitely a reliable source.
Any advice?
