It is an absolutely beautiful day in Baltimore, and it sucks to have to spend most of it inside. Outside feels increasingly dangerous to me. I think it’s the new relatively new call to wear a mask when outside. It’s an acknowledgement that this virus is invisible and could be hanging in the air anywhere, that not even standing all by yourself on a street corner is guard against it. And the masks we’re told to make ourselves, out of cotton, maybe with a coffee or furnace filter stuck in there, will only stop a relatively small percentage of those viruses from getting in. Wear a mask, but not a mask that actually works, because those are (absolutely rightly!) for folks working directly with patients.
