A truly terrible day, IMO.

I too am very busy. I'm enjoying this leisurely, thoughtful discussion. There's a good chance it'll be a while before I have time to give your latest remark, above, the careful reading it deserves. I'm also aware that this discussion is motivating me to articulate a thought I've been developing for many years but don't yet know how to express well, and I need to give that further thought too. I mean to give a proper reply here; I just don't know whether it'll be today, later this week, or (eying the calendar) next year.
