Grand-daddy always said when he was 17
He met the girl, the one in all his dreams
And man that was it, he never once looked back
He found something he just knew was gonna last
And if you ask him bout that day
He'll just tap his chest
And say

That's how you know
When it grabs a hold of you and won't let go
And you feel like she's always been in your soul
And as time goes by she's still surprising you
That's how you know it's true
When a new love feels old
And an old love feels new

He said I walked up to her door
And I was shaking like a leaf there on her porch
Til she flashed that smile at me
And son she took my breathe away
And she still does to this day

That's how you know
When it grabs a hold of you and won't let go
When you feel like she's always been in your soul
And as time goes by she's still surprising you
That's how you know it's true
When a new love feel old
And an old love feels new

And now I finally see just what he means
Cause that's how I feel
Now that you're with me

That's how I know
Cause you grabbed a hold of me and won't let go
And it feels like you've always been in my soul
That's how you know
When it grabs a hold of you and won't let go
When you feel like she's always been in your soul
And as time goes by she's still surprising you
That's how you know it's true
When a new love feels old
And an old love feels new
