It may be because I haven't slept in 30 hours, but I'm having a hard time interpreting your writing

English is not my first language and you haven't slept in 30 hours, that reliably adds up to mutual incomprehension.

Yes, I think it is better in pm. People who read the recent comments would prefer that, i think. The public talks are particularly difficult because e.g. I am inclined to defend the notion that my English is good enough, while you are inclined to defend the notion that non-sleep in 30 hours doesn't impair your reading comprehension substantially. I'll reply in PM.
