The door :
They done changed things around .

Everything changing
All the time ;
Even the air you breathing
Change :
You got monoxide,
Hydrogen—
Changing all the time ;
Skin changing . . .
Different molecules and
Everything .

The door ;
Just saying things change .

As posited :
The air and everything ;
But now
Put two propositions
On the same track ;
Run them together . . .
And because they crash
Call it the same train .

From the air
To the skin
To the door
And now trains—
To many goddamn books .
