Wow, I’ve got to hand it to you: you take more precautions than I do!
I use the mask and wash my hands at least a dozen times. When I get home I drop the keys somewhere, wash my hands like a surgeon, take my coat off and hang it up; unpack the groceries and put them away, wash hands, some plastic stuff I rinse off. After everything is put away I wash my hands again and take alcohol and a paper towel and do the keys the doorknobs, light switches, sink handles. I’ll use clorox spray on counter tops, etc. If I open any new container I wash hands again, etc.
It is all very tiring. As far as mail is concerned, I open it drop the envelopes on the floor, look at the contents. I then take the envelopes off the floor and shred them. I wash my hands again. I’ll usually shower & shampoo soon after. Tomorrow I’ll take alcohol and paper towel for the inside of my car, steering wheel. If all this doesn’t help I give up.
