As I look back at my many decades of life, I realize that the look you present to the outside world can mean the difference between life and death. Consider Jonathan Banks (Mike Ehrmantraut) and Betty Gilpin. Even without a gun, they are able to present a stance, look and voice that tells an invader, don't mess with me.

I have a little perspective on this. I am old. I am retired. And my body aches every where because it is tired and been beat to hell all my life. As I run errands outside of my house I try and think about how I am walking. When my back hurts I walk slightly bent over. If my knees hurt I walk with a limp or shorten my stride and slow significantly. Either of these things make me look older and weaker than I want to appear. So I force myself to walk with my back straight even tho it hurts like hell. I force my stride to be as normal and at a pace that doesn’t say weak old man here. I try to keep my wits about myself and keep looking out around me just in case I have been targeted for whatever.
I am out with my wife regularly. She is disabled and has to walk with a walker now. Her presence says old and weak and I am a target. So when I am out with her I have additional responsibilities to present myself as someone to not fuck with. But it is tough when I am hurting as much as she is. But it is something I try and do every minute that we are out together. Because together we say target even if I am portraying myself as someone to not fuck with. I try to be as self aware as I can possibly be and keep a constant look out in case we have been targeted for whatever.
This is a personal experience I just had this last Sunday:
We had a flat tire and I had pulled into our county library parking lot. The library was closed and there were no cars in the lot except ours. I had called for the service to come change my tire for me. My back and knees don’t allow me to do something this basic any more. While we were waiting my text message said an hour wait. And it was getting onto being dark. Just about that time I noticed a guy on a bicycle circling around on the corner. I assume he was waiting for traffic to clear so he could cross the Main Street. He turned around and saw my wife and I sitting in our car with the trunk open and all the stuff that was in our trunk was out on the ground waiting for our tire service. He stopped circling and started riding his bike right towards us. For what reason I don’t know? I got out of the car and put my hand on my pistol waiting to see if he was coming to us or just going to pass by. I was ready just in case. He got about half way to us and then turned around and left very quickly. This was due to the tow truck that came to change our tire for us. It arrived almost an hour before it was supposed to. I have no idea what this guys intention was or maybe it was just coincidence. Maybe he thought he could be of some help? I have no idea. But I was glad to have protection with me. I never go out without it any more.
I carry every single time I go out. In my experience above we looked like a target because I had left our trunk open and all of our stuff in the trunk on the ground. It was apparent we were stuck. I learned from this. That guy may not have been a bad guy. But he could have been. It is the second time I have purposely put my hand on my EDC because of a situation that I felt was a possible threat. If this ever happens again I will not portray myself as being stuck as I did. I realize this is not exactly the same as your OP, but I thought I would share my recent experience.
