Undefined Value

[Verse 1]
The three green dots on the bottom of the iPhone screen
pulse like a function for a future that we ain't never seen.
It's Tuesday, two-oh-five, you typed, "The silence is deafenin',
can't we just solve this equation, find a brand new beginnin'?
Seven years is a variable, not a fixed point in space, Hale.
We're just two parallel lines that'll never escape this place.
He's askin' 'bout you." The cold glass of the phone sits in my palm,
just another integer added to a fuckin' zero-sum.

[Verse 2]
I typed back slow, "Nah, Sis, you got the whole theory confused.
He's the asymptote—the line that we get infinitely close to
but never touch, that's the axiom, the mathematical fact.
Every call is a regression to the mean, there is no goin' back.
It's a recursive function returning the pain, the limit does not exist.
The proof's in the college fund that vanished, a theorem you must've missed.
So don't you talk to me 'bout vectors all pointin' back to the start,
I'm 'bout to simplify the problem, tear the whole axiom apart."

[Chorus]
Seven years is the constant, the screen is the proof.
I'm solving for X, I'm deleting the root.
The integer's negative, the line isn't true,
so I tapped on the screen, and the variable's you.

[Outro]
Yeah. The variable's you.
Blocked. The variable's you.
