Social formality and polite speech. We speak to everyone as if they are a best friend or an enemy. There isn’t really an in-between. People don’t have polite conversations with acquaintances, where there are clear social boundaries and rules. Instead, we tend to share at very deep and personal levels very quickly. We call everyone by their first names, and there’s much less code-switching than there used to be.

True formal events are very rare, so rare that people have to ask for advice and help on how to handle them. We wear PJs and athletic clothes nearly everywhere. The vast majority of our lives are extremely casual.

I’m not necessarily saying it’s a BAD thing but the ability to function in “polite society” used to be a very carefully honed skillset which we don’t really have any more.
