Measuring the Distance

So I step off a streetcorner and That Must Be
Me, stepping off a streetcorner.
So I step off a streetcorner and That Must Be
What I'm doing. Stepping off.
I perceive myself, stepping. I can feel my foot.
This perception of myself is so palpable that, mentally,
I am somewhere on a streetcorner, feeling my foot.
Somewhere in my mind, I am on a mental streetcorner.
Improbable buildings are balanced around me, there
Where I think of them. That Must Be them.
In my mind, where I think of them, I perceive the word
Buildings: That Must Be Buildings, improbable
As it seems. When, somehow in the course
Of a long day of acting, I perceive the word
Is, I begin to think
The distance. This is a streetcorner. This is
How far to step. Is somehow resembles
A mark on a ruler that I use
To know how far down
To step: is.
That Must Be the distance, is.
That Must Be how far down to step, the distance.
That Must Be how far down I go, how far down it is.
Somehow, in my mind, I know: step down.
So before I step off a streetcorner, it doesn't much matter where,
I measure the distance: this is
Me, though from the cornerof myself, is seems
Somehow always to be
One step down.
