Can You See Her?

Can you see the other person inside me?
She's small and fragile and buried deep,
But she's visible sometimes,
In the flash of my eyes.
She's beautiful, full of light and hope,
But that makes her vulnerable,
And so she's hidden inside.
There's another girl, you see.
And if you listen, you'll hear a peep,
But only sometimes;
There will be happy cries.
I have to protect her, if I'm to cope
Because she's so vulnerable,
And I would crumble if she died.
