3and 5 years olds do something you seem to consciously refuse to do. They learn! They get told that behavior is wrong and they STOP doing it. You however want no responsibility for your behavior and continue to repeat rude and obnoxious behavior then fall back on, I didn't know, nobody told me. Quite a lot of people have told you. Perhaps your parents should take away all your adult toys until you decide to grow up. No more car, no more money( what 3 year old has money?) no staying up, no watching whatever you want to watch, no going out of the house alone. Etc terrible to put your parents in that position
