When I left work in the middle of the day
I didn't tell the boss it was 'cause I couldn't take
This bein' away from you
When I knew you were waitin' somewhere for me
Which you told me on my voicemail as only you could
Had a couple hours off might do me some good
And you know that I can't resist
The way I feel when I think of your kiss

It's blood simple, bone deep
Love's a promise that I mean to keep
Baby you can hold me to it 'til my last heartbeat
It's blood simple, bone deep
Even when I lay me down to sleep

Don't you know that you're the only thing that matters to me
Heartstrong, life long, true blue, blood simple, bone deep

Some things in life you can never understand
And even when you try to describe 'em you can't
Ever say what they really mean
'Cause you always mean more than you can say
That's the way it is everytime I look in your eyes
There's something so pure it completely defies
Any words that I'm thinkin' of
All I can say when it comes to our love

It's blood simple, bone deep
Love's a promise that I mean to keep
Baby you can hold me to it 'til my last heartbeat
It's blood simple, bone deep
Even when I lay me down to sleep
Don't you know that you're the only thing that matters to me
Heartstrong, life long, true blue, blood simple, bone deep

It's blood simple, bone deep
Even when I lay me down to sleep
Don't you know that you're the only thing that matters to me
Heartstrong, life long, true blue, blood simple
Heartstrong, life long, true blue, blood simple, bone deep
