I know everything about you ever since we were kids
We never kept secrets, but there's something that you missed
Came up on North Rush Street, in between the winter days
Ain't it funny how some things get lost along the way?

Just when you thought you got it all
So figured out

What you don't know could hurt you
What you don't know could save your life
What you don't know has been right here
If you just open up your eyes
You don't have to believe everything you're told
'Cause to me all your scars are beautiful
What you don't know could hurt you
What you don't know

I know she tore your heart out, went and threw it on the floor
Don't mean that you're worthless
To me you're something more
Trying to get your attention, it's like water into wine
Guess ignorance is bliss, and even broken love is blind

Just when you thought you got it all
So figured out

What you don't know could hurt you
What you don't know could save your life
What you don't know has been right here
If you just open up your eyes
You don't have to believe everything you're told
'Cause to me all your scars are beautiful
What you don't know could hurt you
What you don't know

I can't sleep at night
Wish you were next to me
More than a friend to me, whoa oh
Can't keep this inside
I need to find a way to tell you everything
Everything that you don't know...

Could hurt you
What you don't know could save your life
What you don't know has been right here
If you just open up your eyes
You don't have to believe everything you're told
'Cause to me all you're so damn beautiful
What you don't know could hurt you
What you don't know... could hurt you
What you don't know can save your life
