Just busily preparing for and dealing with multiple major life changes which are occurring simultaneously and requiring my complete attention without cease. The mere notion of creating even a very high level list to explain my blog absence brings on the sensation of fainting. I can't do it.
You'll just have to be patient and believe that eventually I will return. And I'll have some stories to tell when I do. I'm just too deep in the middle of them all now to have any perspective.
