Bring A Case of Red Herrings to the gym.
During Beanie's gymnastics class, I pulled our trusty Red Herrings ("Solving Mysteries through Critical Questioning") book out of my bag and read one of the mysteries to Jane. As she peppered me with yes-or-no questions in an effort to puzzle out the solution, I noticed the other mothers, one by one, laying aside their magazines and listening in. By the time Jane cried out a triumphant "I've got it," even the off-duty gymnastics teacher behind the desk had given up on paperwork to get in on the fun.
Jane pleaded for a second mystery, but Beanie's class ended before she solved it. Jane and Rose ran into the other room for their class, and I put the book away and joined Wonderboy in his game of scatter-toys on the floor. But the other moms rose up in a body and demanded to know the secret to the mystery Jane had left hanging in the air. I made them guess. Yes-or-no questions only, please.
