So, consensus is wearing a mask protects the wearer, or wearing a mask protects the supposed carrier. Using that logic, you only need one mask between two people, because, If your wearing a mask, I'm safe from you and you're safe from me. If I'm not wearing a mask, it's not your problem, it's mine, and mine alone, correct?
Pile on.
I know I'm gonna regret this but here's the deal:
If I wear my mask, I'm protecting you from my viral droplets. And when you where your mask you're protecting me from your viral droplets. The idea is that we both where the masks to protect each other and help stop the spread. I believe it was Sweden who got their virus stuff under control when everybody masked up.
