At danger of being trite, & acknowleging this isn't the exact scenario you describe:
Family Business - Fish
I heard a battle raging
On the other side of the wall
I buried my head in a pillow and tried to ignore it all
Every night when I hear you
I dream of breaking down your door
An avenging knight in shining armour to rescue you from it all
From this family business
Family business
How long does it stay
Family business?
Oh, it's nobody's business
This family business
But tell me how long it should stay
Family business?
When I see you in the supermarket
Sunglasses in the shade
Averting your eyes from those staring questions
How were those bruises made
The children clutch tight to your legs
They've got so much they want to say
But daddy's at home drunk again
So they bite their lips and pray
'Cause daddy don't like people prying
Poking in his family affairs
And if anyone ask from the Social, well
You fell down the stairs...
It's family business
Keep-it-in-the-family business
Can you tell me how long it remains
Family business?
Oh, it's nobody's business
This family business
Can you tell me how long it should stay
Family business?
She's waiting at the bus stop
At the bottom of the hill
She knows she'll never catch it
She knows she never will
The kids are all she lives for
She's got nothing left to lose
Nowhere to escape to
But she knows she�s got to move
Cause when daddy tucks the kids in
It's takin longer every night
And the heaven that she's waiting for
Through the hell that lasts all night
It's family business
Keep-it-in-the-family business
Can you tell me how long
