True. I'm 60 and have been working since I was 16. Never been unemployed and have only had 4 jobs in the past 40 years. Maybe I've just been lucky, or perhaps it's because I work my butt off to earn my keep. I don't take anything for granted. My current employer could eliminate my job at any moment. If that happens, I have a pension and a 401k to fall back on. Put in the work and the rewards will come.
It most certainly has not. Here's what's really coming. The sun will come up tomorrow. People will get up, work out, eat breakfast, and go to work. Unless they are retired or don't work. Then they'll just go on with their daily lives and do what they normally do. But by all means, hide in your bunker if you feel the need.
Another consideration is that some people are just naturally afraid of guns and seeing them O/C makes them uncomfortable if not a uniformed officer. I know it's more of a "their" problem, but why upset the old lady in the grocery store check-out line unnecessarily? Cover up and stay low-key.
