He's not wrong here. My ultra conservative mom and step dad have been extremely cautious during this whole ordeal and don't step foot out of their house without their masks.
For those of us who have read what is really going on with this bug, it's perfectly natural that you're going to have different responses from different folks. If my wife were still here with us, my personal life would be extraordinarily different from what it is now, as chemo treatments had pretty much destroyed her immune system. She would probably last a couple of days if she caught something like this. As such, I would be doing everything I could to make sure I didn't bring anything into the house.
As it is though, she's already having breakfast with Jesus, and I have a healthy and robust immune system. I'm taking no precautions at all, because the likelihood that this will affect me adversely is almost nil.
Even if she were around, and threatened, I would not be demanding that everyone else be as justifiably paranoid as I would be for myself and the love of my life.
