Our family doesn't eat indoors, doesn't go into buildings unmasked, wears masks in dense outdoor situations, wears a full elastomeric mask when flying.
For the past few weeks, even when outdoors, I've seen a few friends coughing, and I immediately put my mask on. They then say, "No dude, relax, it's not Covid, I tested this morning!" And I said, "🙅🏿♂️ Sure! That's what 'Rona *wants* me to think! 😷" 4 friends this happened with, and all 4 tested positive the day after their little coughs.
