> I think the fundamental problem with noisy people is (...) that they don't have any train of thought to interrupt

I must say that this choice of words rather took me aback as well. The problem is, it's difficult to call someone breathtakingly arrogant (which was my first reaction) when they have so much to be arrogant about!

I'd love to see some more insight on this from pg.

Edit: It's since occurred to me that pg may have meant at that particular moment rather than lacking a train of thought in a general sense. If that's the case, my comment is unjustified - apologies.
