Well, people really do need to get it together and use common sense. I have a family member that tested positive along with her boyfriend a little over a week ago. I was checking on them yesterday, and she tells me that he is "out and about", and I'm thinking like, "what the heck".
Even if you live alone and are about to starve, you can get groceries delivered in most areas, and even if I were about to starve to death, I'd be double-masked, and doing like the old lepers in bible times, telling people I'm positive, and that they should stay far away. I don't get folks putting others at risk in this manner.
