Jordin Sparks explains best...

One word turns into a war
Why is it the smallest things that tear us down?
My world's nothing when you don't
I'm not here without a shield
Can't go back now

never meant to start a war
You know I never wanna hurt you
Don't even know what we're fighting for

Why does love always feel like a battlefield
A battlefield, a battlefield?

Can't swallow our pride
Neither of us wanna raise that flag
If we can't surrender then we both gonna lose
What we had...
