```          Back in the old days
Folks were so certain
Predestination
A path of God's choosing

Along came the men
With their proofs
And their theorems
All of it got just a bit more confusing.

I really would like to create the equations
Define our relations
With one derivation
Here is my question on many occasions,
"What does she want me to do?"

It would be great if life weren't so complex
We'd make an index
Find a number for x
How can I calculate all the effects
of simply my being with you?

Newton defined things
In terms of equations
Took Aristotle and
Swept him away,

Einstein took Newton's work
And everything changed
In a relative way.

Part of me wants you to make up your mind
To tell me you're mine
Or leave me behind
Sometimes it feels just a little unkind
Never to know where I stand.

Sometimes I think that I'm asking too much
My questions are such:
Am I just a crutch?
I really can't tell if you're missing my touch
And nothing quite goes as we'd planned.
