I was treated as an adult by almost everyone my whole life. That is only when it could be used to blame me for something, or shirk responsibility for not doing something having to do with me. It was real Spartan for me.
Everything I know I got on the streets one way or the other. I still learn things I should have been taught then every once in a while. I resented it only when I began to realize I had been deprived of it. Until then I asssumed I was defective for wanting to be taught and that was encouraged.
As Mark Twain once quipped, history may not repeat itself, but it does rhyme.
