I see your point. I guess the issue is the depth or extent of the socializing.
The challenge is that with close friends, you probably have a better chance of getting timely info(hopefully) if one of them is at risk and that you could also be at risk and what yo do with that knowledge.
In your example, would you feel as comfortable as you do fishing if instead you and your fellow workers decided to go to one's house and have a beer and a pizza.( Sitting at a long table
My concerns and they may not be valid, is that not only are the folks you interact with a factor but so might be the number of interactions with the the same people. I am not trying to start an argument, I just don't really know what the best policy is.
On a separate note, is your work place taking extra precautions and if so, does that make you feel safer?
