Aubrey Plaza walked her dogs, outside, by herself, and wore a mask. If there are no other people around why are you wearing a mask. Are you protecting yourself from Chemtrails? I can only assume that's the reason, especially since that's not a medical mask so it isn't stopping the virus even if it was floating around freely in the air, which it's not because that's not how a virus works. Maybe it keeps her from licking mailboxes or something else someone else may have touched five minutes ago. Or maybe it's acting as one of those cones people put on dogs so they don't chew themselves, did she get any sticthes recently? Maybe it keeps her from eating random things off the street. I have a cat that swallowed a nickel once and needed very serious surgery so that might actually be smart of her.
