Rhyme scheme irregular;: A-B-C-B-A-D-E-C-F-E-D-G-F-G.

There are advantages of irregular schemes. the rhyme binds the verse, as it does in a more formal scheme. But it was less obvious, and so feels less "forced."

While I like all the forms that make up poetry, I'll toss them all out if they hold the poem's meaning back.
