sometimes i wonder if people really mean to litter? I see a few cloth masks on the ground too, I assume they fell out of their pocket ect so my guess is that for the most part people take the masks off on the way to their vehicle, of course when no one is near by, and the light masks fall out of their pocket or blow away ect
I'm sure a few people don't care and I get skeptical too but I choose to think most people are decent so I try to assume the best until proven otherwise
