It took a while to reply, and when I got round it I could not find
anything new that seemed to be worth saying.  I think we've both stated
our positions quite well.  I don't think we will end up in agreement,
and whilst I can grumble and nit-pick as well as anyone, with the big
picture left to one side there only seem to be such details left to fuss
over.

I hope, therefore, that you will forgive me for not replying in full,
but I none the less do thank you for taking the time to talk these
points over in depth.
