My daughter. She works in a hospital and has works the covid ward about twice per week. She's seen what it does and she's seen people die from it. And she had to fly to Vegas on short notice and said she would rather be working the covid ward instead of flying on a plane.
Early on, before masks were mandated, her hospital couldn't get N95 masks, but people were squeezing cantaloupes at the grocery store wearing one. Also...my barber shop was pretty lenient even after the mask mandate, and wearing one was optional. Then one of the barbers got Covid from a client. So things change. I wear a mask now so that maybe my kid will have one less patient to deal with.
