While I wish I had a fraction of soz's diligence in finding answers I confess to being a bit more like Linkat - coming up with some rather outrageous answers to outrageous whys.
That's a very good point, Linkat, about information you're not quite sure they really are ready for, certainly something to consider in the future.
Mo is a control freak, some days way more than others so I'm thinking your comment, Noddy, on control might have a lot to do with it.
Yesterday we had a "mean Mo" day and the "why" was fast and furious with nary a gentle giraffe neck topic. Control indeed.
