An aside: a student brought a poem to workshop last night that was brilliant--a dictionary rewrite in the vein of A. Van Jordan's in M-A-C-N-O-L-I-A, & in the middle of a lovely poem was a line so coarse, so crude, it was frankly shocking. I spent ten minutes thinking about it--did it belong there, or was it *too* crude for the poem? In the end I decided it'd earned its place, and majestically. But either way, to reconfigure your reader's expectations so dramatically, it's a brilliant success.
