I think some people wear them because they want to show the world how much they care or they are terrified of some loon yelling at them. Which, if it happens, tell them to fuck off...others do it strictly because they fear for their lives when they walk outside their house. I have neighbors who were outside raking leaves a month ago (father and teenage son) both of them masked up on a 70 degree day while outside. They live in the same house! Saw another neighbor walking her dog while wearing a fucking face shield. I feel like Im the only sane person around this area some days. I need to move to Idaho, Wyoming, or Montana away from humans lol
