I'm writing another poem about my son, this time, about how well his lithium is working. I like to weave beautiful language with scientific terms, so I Googled "Lithium." Interesting! http://en.wikipedia.org/wiki/Lithium_carbonate I may have gotten myself in too deep ... how to bring in red glaze, oven safe cookware and cathodes to this poem, when my original focus was the calm use of language? I think two separate poems might work best. Anyway, it's a fascinating topic.
