Lori, LeeJ, JerryPat2- Thanks, I'm glad you enjoyed this piece. Great feedback, btw.
This poem has to do with what can happen after studying dry and mechanical subjects or topics for too long. For example, in college if you specialize in something like one of the hard sciences or scientific writing. The mind becomes akin to a black/white machine, robbed of certain colors of imagination it had before. Your storytelling ability and vocabulary, although enriched in scientific jargon, may become limited in other ways.
