Now, you apparently want to pretend that inappropriate snideness isn't obnoxious

Not at all. The fact is that I intended no snideness at any point. In fact, reviewing what I wrote, I don't even see how you could read snideness into it. But no matter: I'm sorry you took it ill. That was never my intention.

You said I was wrong (about exactly what, only you could know) in your first reply to me here, compared it to science fiction, then proceeded into a nonsequitur where you get Bob moving really fast. I guess I should congratulate you on not slacking off from that initial pace.
