How do you know me?

How do you see the parts that I hide from the world, the parts that I hide from even myself? 

I hide behind laughter 

I hide behind being the party girl

I long for acceptance 

I long for what might have been.

But how can I get that if no one knows the scared little girl I am.

But somehow you see me.

How do you know my soul?

How do you know me?
