It's just hilarious to try to keep up with their changing minds.  That's because they're ALL complete and utter lunatics.

It's also part of the game they're playing with people.  The more often they change the rules, the more confusing it becomes and people don't know what they're being "ORDERED TO DO".  Just do whatever you feel like doing and you'll be fine.  If you want to wear a mask, for God's sake go fot it, but otherwise just ignore all the gubmint edicts and the CDC, too.
