My life is based on a true story

I'm just a girl:
I love being called pretty, but I'll never believe it.
I'm not always right, but hate admiting I'm wrong.
i'm almost always smiling, but it's not alwyas real.
i can be read like an open book, but hide so much,
I work hard at things, but don't always get what I deserve.
I'm just a girl.
