I wanted to be a "grown up" so I could do what I wanted to do...not what I was told I should do or could do.
But not all of us are alike. Apparently some children grow up and still NEED/WANT/REQUIRE being told what they can/cannot do or think or say. That's why there are groups of like-minded ilk with strict rules. Political parties are among the most notorious of the genre. Also hate groups. I mean you can't be a good Nazi and love humankind without exception. Your hates have got to be in line with the philosophy of the group.
So kids do what they are told to do. Many adults do too. Extended childhood or arrested development?
Some or possibly many grownups do what they are told to do to believe in to espouse and luxuriate in it. They are just old kids aren't they? Never grew up to decide for themselves but immediately got sucked into some group that told them what they could/could not do/think/say. The "leaders" are the parents with strict rules that you will follow if you know what's good for you.
And so it goes.
