Sincere thanks for so reasoned and courteous a response, Marianne. I hope you may return in a few days, to develop some points, to which I might rejoin, and some sort of productive interaction might ensue. In fairness to myself, I think I must say that made no such assumptions as postulated in your sentence above about your 'personal circumstances'. You must admit you did positively decline to answer on the plea of the impenetrability of my 'carapace of certainty'.

Still, let us proceed from here, as time and commitments may permit.
