How Little We Know - Frank Sinatra

How little we know
How much to discover
What chemical forces flow
From lover to lover

How little we understand - what touches of that tingle
That sudden explosion - when two tingles intermingle

Who cares to define
What chemistry this is
Who cares with your lips on mine 
How ignorant bliss is

So long as you kiss me - (and) the world around us shatters
How little it matters - how little we know
(How little we know, how little we know,...)
