It seems like everyone thinks that wearing masks is only to protect themselves from other people, and completely forgot (or never learned in the first place) that it's actually arguably even more important to wear a mask to protect others from your own cold, whether it's COVID or not.

This is something I really love about Japan and Korea. People are very considerate about not spreading their germs around in public places, by wearing a mask when they're sick.

It really feels like the rest of the world missed that part of the memo, even though we all wore masks for an entire pandemic. It actually boggles my mind.
