I don't want to harp on this much more, but after Day 1 of my kids being back in school, I figured I'd give it one last go. Here's why it's selfish of you to not wear a mask.
I am sure you are clean and healthy and all that, but someone out there is sick. You might believe yourself to be strong-like-bull, too smart, or immune. Or you're ancient and think it's your time when it's your time. Please, feel free to play roulette with your 2nd Amendment souvenir, away from the rest of us. You are not too smart, healthy, or clean to catch a virus. You might well survive it, or you might never even know you had it because you're such a freakin Adonis. While you are asymptomatic, possibly for weeks, you could infect dozens of people because of your odd belief that viruses respect your freedom and patriotism and religion.
