Noise, noise, noise

My neighbour and her daughter (9yrs old) have been screaming since the time I reached home (6pm) until now. It is late okay, @ 11.10pm. And her little girl has just slammed the door.
I know that it is none of my business, but I can't help it.
About 2 months back, the noise was so unbearable that I had to called the police to check on the
girl. For 2 weeks I would hear them fighting and the girl crying & wailing like she's been raped,
or roped. When the police came, they confirmed that it was noise from the neighbour,
but then classify it as domestic dispute.
Later that day, I heard the girl screaming & shouting at the mother, but then no response from her. Then it dawn on me that the problem is the girl.
And true enough, from that day onwards, I only hear the girl's voice screaming & shouting at
her mom. She's only quiet when her dad comes home.
And now, it started again. Both mom & daughter having shouting match with each other.
Can you imagine the noise??
I can understand when family have their arguments, and once in a while, fights.
But please, not every day & night!
We are living in close proximity. Even though behind close doors, we can still hear each other.
You don't have to put much effort to listen, cos' we can & do hear things being said.
I wish the mom will just slap her silly. From the looks of it, the girl is the tyrant, and using screams & tantrums to get her way & bullying the mom.
Whenever I meet them at the corridor, I will greet the mom, and look straight at the girl.
I want her to know that we hear the noise she makes everyday.
I've ever bluntly asked the mom if she heard child screaming & shouting.
The mom naturally denies, but I can see the girl throwing a dirty look at me.
Well she can hide, but not for long. One of these days, her mom will snap, and she will
get the taste of her own medicine.
Ahhhh................... peace at last. No noise.........
I guess she's tired cos she got morning school.

Finally, peace at last ...........................................................
