When there is a public health emergency, a declared national emergency, whose job is it to make sure everyone stays safe and has the info to protect themselves? I've said before the govt can send out post cards, put posters in grocery stores and post offices. Makes sure people who don't have internet get informed.
When all this first happened a friend of mine shared on social media how he was in the store, crowds were out the door and there was this one elderly woman who was frail and confused. She didn't know what was going on, was overwhelmed by the throngs of people and only wanted to buy three things. He said she seemed a bit I'll so no one was going near her and she seemed like she might pass out. He helped her get her items and walked her to the car. He told her a bit about what is going on. I'm sure there are countless others in this situation, just like there were countless elders who don't cook for themselves affected by restaurant closings etc.
There's people poor behavior and lack of understanding doesn't relieve you from the call to do the right thing when you know the right thing to do. You can't speak to everyone, folks are hostile and resistant to knowledge, but for people you have relationship with, why wouldn't you educate them on the proper way to stay safe, wear a mask, etc?
