You don't know the things in your childhood that influence you. You can't possibly know them. People today try to analyze the early environment and the reasons for something that happened, but if you look at children of the same family -- children who have identical parents, go to identical schools, have an almost identical upbringing, and yet who have totally different experiences and neuroses -- you realize that what influences the children is not so much the obvious externals as their emotional experiences. Of course any psychiatrist knows that.
