LOL!! I grew up in the 50's, and was the baby of the family, so I got away with far more than my siblings did. I thought I knew it all too when I was a teenager. What my mother told me went in one ear, and out the other, but when I became a mother at 19, reality set in, and I woke up to what responsibility is really all about. My mother used to say that the older us kids got, the bigger the problems. And back then I never understood why she couldn't go to sleep unless all of us were back in the house. When I had my own kids, I totally understood where she was coming from. I think because neither of my sons have children, they have no idea how much a parent worries about them, no matter how old they are.
In my case, it was because:
1. Dad didn’t care except where my behavior made him look bad or otherwise reflected on him.
2. I’d long lost any respect or awe for him, because he was and is emphatically a do-what-I-say-not-what-I-do type.
Between those two, plus a literally psychotic mother and other family problems, I ended up having to function as an adult before I hit my teens. I was basically marking time until I graduated and got the hell outta there. The only thing to do was to endure.
