Honestly? I wouldn't assume everyone knows about it.

I haven't been wearing a mask because frankly I haven't really heard anything about it. It might be on the "airwaves" but (like most people under 40) I don't listen to the radio or watch regular TV. I don't see anything about it on the PPH homepage. Haven't heard anything about it from the kid's school.

I'm not saying it's not an issue, and if I search for the headlines I can find them, but I don't think it's as everywhere as you think, especially for people who aren't regularly consuming a lot of local news (which I would assume is most people).
