Not everyone that you speak to is objective or level headed.

Maybe they're low-sugar and crashing. Maybe their dog just died.

You have absolutely no way to prepare for all of the ways someone will be ill-equpped to handle their day. And this is probably a high percentage of people at any given time.

But we can't afford a society where everyone treads on egg shells.
