When I was about 16, my favorite book was The Unoriginal Sinner and the Ice Cream God by John R. Powers. His more famous work is “Do Black Patent Leather Shoes Really Reflect Up?” He’s a Catholic writing about growing up Catholic. I’m not Catholic but I really identified with the main character, Tim Conroy, a male growing up and trying to figure things out, separating the standard adult speak from reality.
Conroy meets a mechanic/gas station owner, Caepan, who says he could do a better job than God. They begin a correspondence, the young man writing to him as though he is God and dropping them off, then retrieving answers on his way to school.
One exchange, paraphrased:
*Conroy: When do child ownership rights expire?
God: I once had a son. When he was no longer a young boy, but a young man, I said to him: "Son, make no mistake about it…for the first part of your life, I did everything for you. I made your life possible. I would have lived without you, but not nearly as well.
<stuff I’ve forgotten>
If we meet after today, let it be because we are friends, not family.*
I think that’s what you want to aim for, OP. Kids grow up and realize that a lot of the discipline was for their own good. They know they needed to be hassled, kept on track, etc. But ultimately they want to be treated as adults, as peers. No, she doesn’t have your experience…yes, she’ll have to learn some things the hard way. But that’s the way it works; weren’t you the same way?
The parents’ job is to put themselves out of a job. Legally she’s an adult now. You can be there when she has questions or needs support, but let her try her legs. You should congratulate yourself on getting her to 18 without too many major scrapes. But now she has to make decisions on her own and they’re hers to live with.
