Girl inform me

Girl, inform me all my senses warn me
Your clever eyes could easily disguise
Some backwards purpose
It's enough to make me nervous
Do you harbor sighs, or spit in my eye

But your lips when we speak
Are the valleys and peaks of a mountain range on fire
So let me walk these coals 'til you believe
I can cut the mustard well enough
'Cause you know as soon as breathe we scrutinize

Unknown quotients, you must be using potions
How else could you tie my head to the sky?
This new convection has left me wondering why
I can't concern myself with ordinary tripe

Like what's this morning's paper got to say?
And which brand of coffee to make
This is no umbrella to take into the wind
But before we begin, is there nothing to kill this anxiety? But your lips when we speak
Are the valleys and peaks of a mountain range on fire
So let me walk these coals 'til you believe
I can cut the mustard well enough
'Cause you know as soon as breathe we scrutinize
The paint away
