On the way to school the Penguin chain-pull on Oyon's book bag got caught in the car door. He recovered it before we drove off but we spent the ride to school making up a giggly tale about what might have happened if he hadn't. This preamble is mainly in defense of the liberal use of behinds (and all it's 7 yr old synonyms) in the tale. I may have been driving the car but 7 year old scatological sensibilities were steering the story.
