Everybody wants to find a love
Somebody, somebody who will always care
But we get locked up in our own worlds
With feelings and secrets we're afraid to share

But all I have to do is see you smile
Or maybe, just maybe if I brush your hand
Something happens I cannot explain
And somehow, oh somehow I can understand

I, I think you're gonna find
I'm gonna find you
I'm gonna find you
I really don't know how

I know you by heart
You're so much a part of me
I know you by heart
Can't you see?

It's no wonder I can love you
The way that I do
I can finish any sentence you start
Woah, I know you, I know you by heart

I know every time you wanna call
I pick up the phone before it can ring
And when you need some lovin', I'll be there
Beside you, anticipating everything

Oh, it's like I always said
You're the one I want
And all I want is you
I'm inside your head

I know you by heart
You're so much a part of me
I know you by heart
Can't you see?

It's no wonder I can love you
The way that I do
I can finish any sentence you start
Hey, woah, I know you by heart
I know you by heart

So much a part of me
It's no wonder I can love you
The way that I do
I can finish any sentence you start
I know you, I know you by heart

I know you by heart
So much a part of me
I know you
So much a part of me

I know you
So much a part of me
You're such a part of me
I know you by heart

Yeah, I know you by heart
You're so much a part of me
So much a part of me
I know you by heart
You're so much a part of me
