Most people are moated, particularly those society deems worth engaging. This means there are barriers to getting into their life and often these barriers are insurmountable. I have been in situations including a college surrounded by people society deemed worth engaging and it was generally useless trying to get into their lives. It’s only gotten worse as I’ve gotten older. The only people that don’t seem to be moated are people on the spectrum and a subset of those who struggle with mental illness.
Of course no one tells you this fact. This is because it is one of the unwritten rules society is ashamed of.
