Lying heart still

Baby girl I
Always said that I never could lie
But that's a very good lie
I mean how else could I
Keep you in focus like my good eye
Keep your ass from knowing
I'm not a truthful guy
I've got no reason why
You want to build a better world
I'm not the one who should try
So if I ever said I love you
You better get it on paper
I'd probably shock you with deception
And have to de-fib you later
