Graham, I have been monitoring all of the postings on this website and have noticed a lull in the dialog, as you have. Some postings never receive a response while others have an initial burst of activity and then fall silent. I believe that you and I may be able to stimulate more participation by getting to know each other. Although I have not been diagnosed with Asperger's, I know I am on the spectrum. I will soon be seeing professionals who can make such a diagnosis. Let me begin with something from my childhood - the first part of my story. (I'll keep all of my postings to one or two paragraphs so as not to bore our readers). I am 52 years old with two younger brothers. When I was less than 8 years old, my parents noticed I was a little different than many boys my age. One day in the early 60s, my father gave to me an insert from National Geographic Magazine. It was a star atlas poster showing all of the constellations in the northern and southern skies. I was so thrilled with this poster that I memorized the names of every star and constellation. My father gave me his binoculars and I spent many hours, days, years studying the stars, trying to identify every one. This was the first of my many obsessions. Cheers, Dennis
