Lipstick stains on a Starbucks cup
Strong black coffee in a Thermos jug
Take two soft hands and two that are rough
And it all adds up to us

A BMW and a GMC
One says "her" and the other screams "me"
One for the road and one for the mud
And it all adds up to us

From the outside looking in
The numbers don't work, no, it don't make sense
They can't figure out how we love this much
But it all adds up to us

Runway model meets FFA
Uptown style and the cowboy way
Take her sweet voice singing and the way I cuss
And it all adds up to us

From the outside looking in
The numbers don't work, no, it don't make sense
They can't figure out how we love this much
But it all adds up, it all adds up to us

My old blue jeans are laying on the porch
Her little black dress is on the kitchen floor
Take a whole lotta love, plus a little bit of lust
And it all adds up, it all adds up, baby

From the outside looking in
The numbers don't work, no, it don't make sense
They can't figure out how we love this much
But it all adds up
Yeah, it all adds up, baby, to us

It all adds up to us
Yeah, it does
