if you're normal you don't need to act normal. only other people acting normal will pretend to believe you. the more you act normal the more you see how strange it is, the more you realize you don't know how to act, and there are so many bad actors, who don't know how to act, acting badly. this is the problem with trying to fit in. the feeling of having to do something gets in the way. under ozmotic pressure people can quite suddenly flip. maybe the purported goal was to give everything you have but it gets confused with taking everything you can get. we try to behave normally but we all humans are in trouble.
