On the surface it looks like a bender. I don't know the facts so I'm I'd reserve my judgement. It also sounds like at the first sign of symptoms they've acted appropriately and isolated themselves.
However, I agree that I have less sympathy for people who would be deciding to go on bender during a pandemic as well. If we are behaving as we "normally" were, then it's probably not right.
You've hit the nail on the head about how dangerous this is and the responsibility we all have. We all should, have and will continue to have to make sacrifices.
The sad death of two men in their 30's is hopefully the wake up call needed to demonstrate the "younger" people in our community are not immune or pre-disposed to a "mild case".
