> Nowadays carriages are split between 'normal' and 'quiet'... And the number of quiet carriages seems to have increased over time... It's like there are forces in society which try to prevent people with different experiences from sharing their experiences.

In the USA at least, people in the normal cars aren't "sharing their experiences". They're playing garbage music from their iPhone speakers (technically not allowed - happens anyway), trying to subdue their giggling/crying/screaming children, loudly conversing amongst themselves, etc. It's a zoo.

Not trying to pick apart your post, I liked reading it in general.
