I'm usually a bubbly girl but..        Hush, little sister
Please don't cry
I wish I could be there
To sing you a lullaby

I can see your arms
Bloodied and bruised
That's strange, little sister
Mine were like that too

I know you scream
When Daddy's there
Hush, little sister
I know you're scared

I can see the way
He's hurting you
I'm sorry, little sister
He did that to me too

I know that people
Ignore what's going on at home
That makes me angry, little sister
You shouldn't have to be alone

Hey, little sister
You want to know why I'm not there?
It's a sad story, little sister
But people should care

You see, little sister
One day Daddy got high
You were asleep in your crib
So you didn't hear my cry

He screamed at me
And smashed my head against the door
While you slept, little sister
I died on the floor

You know, little sister
I don't think that I would have died
If someone had only bothered
To listen to my cries

But hush, little sister
Daddy's coming home
Quick, get into bed
You don't want him to find you alone

I'm sorry little sister
He's in a bad mood
Run while you can

Uh oh little sister
He's lifting his belt
Scream while you can, little sister
Call for help

Hush little sister
You don't need to cry
No one can hurt you
You're in my arms tonight.

Also here's a nice one 

Be who you are
Say what you feel
Because those who mind don't 
Matter but those​ who matter don't mind
