I've got you sister...

;)
... Always....

(...)
We've taken different paths and traveled different roads
I know we'll always end up on the same one when we're old
And when you're in the trenches and you're under fire I will cover you

If I was dying on my knees
You would be the one to rescue me
And if you were drowned at sea
I'd give you my lungs so you could breathe
