I am a quiz  to which you know all the answers
I am a road map to which you know all the routes
I am a song to which you know all the lyrics
I am a movie to which you quote perfectly
I am a river to which you know the current  

You see right through me
I know I give it all away by just the look in my eyes
How you leave me with shaky thighs
How I hang on to your every word
How nothing you say to me goes unheard

I've never done mysterious well
Especially with you
I tried so hard to keep my guard
Yet somehow you left me an open book
But acknowledging it is different
So instead we can keep it an unsaid secret
