My daughter explained to me back in April that I needed to do so to protect my guardian angel. While she believes guardian angels wear masks, two masks are better than one.
If this is a virus angels (and demons) can catch, that moves things into a whole different threat level.
As my daughter is 7, this is excusable, but something only marginally less weird than most of the government. And less weird than Pennsylvania, and possibly NY.
Precious. I raised 3 daughters, that age is fantastic.
