The possibilities.

Though I may ruin this for her

You'd thank me in the end

For though she smiles bright as day

She's lost inside, a bit insane

And you could have her at her best

But time puts reason to the test

And she'd be gone before you knew

And you'd be fighting for the truth

She'd run away, she'd let you in

She'd find a way to say she'd win

She'd let me take the reins again

I'd cut you off, no chance of "friends".
