Imagine, yourself-no, be there! -in a canyon,
Crisscrossed with sharp steel edges,
Rim to rim,
The Grand Canyon of canyons;
You're at the bottom-
There is no way out
Unslicing yourself.
That's the blues, not the greens,
(Like the colored wedges) ,
You feel wedged in every day
In the canyon of imperfection.
