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 [ Lyrics from: http://www.lyricsmode.com/lyrics/f/frank_sinatra/how_little_it_matters_how_little_we_know.html ]
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,...)
