I was listening to the radio yesterday afternoon and the presenter was talking about catching up with her children over the Christmas holidays: she spoke about their inquisitiveness and questions she couldn't answer - such as "Mummy, why are clouds white?". Have you considered producing a QI book for parents and children who want those baffling questions answered? Not sure how you would choose to answer the "Mummy, who is God/where is God?" question but perhaps it could be fun and interesting devising answers in the faith-zone specifically for any parent/child of any denomination. Also wondering if there is space in such a tome where parents contribute their best answers.
For Christmas 2012...? Perhaps...
All good wishes
