The biggest lie you ever told
Your deepest fear 'bout growin' old
The longest night you ever spent
The angriest letter you never sent
The boy you swore you'd never leave
The one you kissed on New Year's Eve
The sweetest dream you had last night
Your darkest hour, your hardest fight

Chorus
I wanna know you, like I know myself
I'm waitin' for you, there ain't no one else
Talk to me baby, scream and shout
I want to know you, inside out
I wanna dig down deep, I wanna lose some sleep
I wanna scream and shout, I wanna know you inside out
I wanna take my time, I wanna know your mind
Ya know there ain't no doubt, I wanna know you inside out

The saddest song you ever heard
The most you said with just one word
The loneliest prayer you ever prayed
The truest vow you ever made
What makes you laugh, what makes you cry
What makes you mad, what gets you by
Your highest high, your lowest low
These are the things I wanna know
Chorus:
I wanna know you like I know myself
I waiting for you there ain't no one else
Talk to me baby, scream and shout
I wanna know you inside out
I wanna dig down deep, I wanna lose some sleep
I wanna scream and shout, I wanna know you inside out
I wanna take my time, I wanna know your mind
You know there ain't no doubt, I wanna know you inside out
I wanna know your soul, I wanna lose control
C'mon n' let it out
I wanna know you inside out
Ya gotta dig down deep, lose some sleep

Chorus:
I wanna dig down deep, I wanna lose some sleep
I wanna scream and shout, I wanna know you inside out
I wanna take my time, I wanna know you're mine
Ya know there ain't no doubt, I wanna know you inside out
