For all the folks who don't have masks, don't like bandannas around your faces, and aren't that crafty to where you can make a reusable mask, old cotton T-shirt sleeves work great. I actually prefer shirt sleeves over bandannas, now.
For those folks who wear masks in public, thank you for doing so.
For those folks who don't wear masks, no, they aren't mandated where most of us live. But neither is covering your mouth when you sneeze or cough. Wearing a mask is polite, and helps others from catching your saliva. You could have it, not know it, never get sick, and give it to someone who could get very sick and die from it. The more people who wear them, the less the virus can be transmitted.
I wear one for you when I'm out in public. Please show me and others the same respect.
