Two weeks ago, my wife set up an outdoor picnic for a friend and her family who were stopping by for a visit during a cross-country trip. They were too scared to come indoors and all wore masks, even outside. A week later, she texted my wife that she tested positive for the virus after experiencing very mild symptoms. "Why would they tell us to wear masks if they don't work?" she asked my wife.
