I'm not anti mask, just in favor of truth in advertising. Here's the thing about possibly infecting your spouse, as in the op, if you wear a mask every where you go you reduce the possibility that you will infect the clerk at the lumberyard, but you have not significantly reduced your ability to become infected, yet you go home and refuse to wear a mask in the house and bang you've done got a benign case of cov19 and given it to your spouse and yep she dies. Well she can't blame you can she? you wore that mask and didn't infect the public.
