While I do not disagree with anything on the above lists, it all comes down to situational awareness. I do go out alone at night, but I think about where I Park and where I walk. Yes, the world can be a scary place, but it is also a wonderful place full of experiences and good people that I want to enjoy and not live in fear.
Having a wife and two adult daughters I am aware of the risks they, and anybody, face. I taught them to be aware, use common sense and error on the safe side if any doubt.
Go out and enjoy life,. It is a big wonderful world that is mostly safe and fun, but think about where, when and who you go places, but don’t let fear and anxiety make life miserable.
