To which I’d add:
Oprah Winfrey once did a show on personal safety. One thing she said always stuck with me. It’s something I’ve since mentioned to all my relatives:
“Your safety comes before their feelings.”
For example, if a guy on a sidewalk looks wrong, go ahead and cross the street. Don’t worry if that offends him.
Or, if a guy in an elevator looks wrong, don’t take that elevator. Don’t worry if that offends him.
We moved around the country a lot growing up so I was more or less situationally aware without realizing until college that’s what it was called. Moving taught us, among many things, to size new people up quickly - to stay away from some people but others might become friends. I was always in protective mode. Still am.
