AIBU to think that people are trouble and contact with others (aside from family and friends) should be pretty much non-existent, only taking place when unavoidable & absolutely necessary, such as work (but only those you have to talk to, & only as briefly as possible.)
I have realised during the pandemic how little value external contact brings to my life; people are complex, & lots of people are just out for what they can get from you in my experience; they owe you nothing & unless you put these rigid boundaries in place you’ll end up giving more energy to negative or pointless interactions than is healthy.
I just find people too complex as well; life is so much simpler & focussed with less people in it apart from family & friends. As a last point, the other thing I’ve observed is how hostile the world has become. People are on their guard these days; they want to be angry and if you put yourself in the firing line you’ll get roasted. It’s just not worth it. Contact with others costs too much.
Best to cut contact, mind your own & keep well away!
