out of nothing at Chemistry

I know just how to whisper
And I know just how to cry
I know just where to find the answers
And I know just how to lie
I know just how to fake it
And I know just how to scheme
I know just when to face the truth
And then I know just when to dream

And I know just where to touch you
And I know just what to prove
I know when to pull you closer
And I know when to let you loose
And I know the night is fading
And I know the time's gonna fly
And I'm never gonna tell you
Everything I gotta tell you
But I know I gotta give it a try

And I know the roads to riches
And I know the ways to fame
I know all the rules
And I know how to break 'em

And I always know the name of the game

But I don't know how to answer these Chemistry Questions,
and i never let myself fail,
and i never know how you do it,
making my life worse out of nothing at all
