Shortcomings....?

Isnt funny, you were taught as a child, "do this , dont do that" and in adult life, many of those things just dont make sense? Like in school, you are told to be quiet, when its in the nature of young people to be restless and talkative? Like when parents used scare tactics instead of love to guide you? "just wait til your father gets home" i just find that so many things taught to you as a child, we as adults have to unwind and undo some of the damage our parents instilled in us. we live in a world where too much is not too good. i suppose when we realize that many shortcomings of our parents were just "the best they knew how with what they had" isnt good enough. So as adults we have to undo what was done in ignorance to us and not p some of it around. what is your take on this subject?
