I've made the mistake between baking soda and washing soda - I sent the mistaken batch (I was making my own washing detergent) to Linn (Bat Goddess) who added the right kind of soda and used it. (I realized the Naptha soap I grated into it was a coconut base, and I'm allergic to coconut).

I just logged onto the CVS site and see that my test results are negative. !!! (There is the usual proviso - you could be very early in your infection . . . but I think not, in this instance.) My exposure, as it was, was outside several feet from the sufferer.

I'll be all the more careful to wear my mask everywhere I go and stay socially distant. It's almost feeling like time to start ordering groceries again. But I'll go get my baking powder first.
