So I was that person yesterday.... driving in my car with my mask on with my daughter with her mask on, all windows down.
My daughter is diligent about mask usage (she treats covid patients), I have rarely been in her home since March (and wore a mask when I did - to check out paint colors in the basement).
So yesterday she needed a ride, and jokingly I said, are we gonna wear masks. And she said yes, etc...
Note: We don't wear masks when we are outside, walking or taking the kids to the park. At one point we did, but haven't for several months now. Carry hand sanitizer and disinfectant wipes and use as I feel necessary.
