Haiku are three line poems of 5, 7 and 5 syllables first composed in 17th century Japan. A friend and colleague who writes haiku urged me to give it a try. I laughed and said the analytic (left) part of my brain is so overused compared to the creative (right) part of my brain that I probably tilt slightly to the left when I walk. She persisted, though, so I went on to suggest that writing bad haiku is probably one of the easiest tasks in literature and writing good haiku one of the most difficult.
