A favorite William Carlos Williams poem:
Leaves are graygreen,
the glass broken, bright green.
That's it. Nothing more. A slight thing, eh?
In 1999 and 2000, when I taught my English 88 course all online, I prepared a 2-minute audio recording of me and the poet Shawn Walker discussing this poem, as a way to get our students to begin to understand Williams' passion for the unnatural as a form of the natural.
