If you would just treat your teenager like a person instead of a toy that will suddenly become a person, this wouldn't happen. Schools are designed with that idea in mind, that children are toys, and so the goal is "memorize this thing that you should care about, what do you mean i should make you care about it? You should just care about it", because we're not seeing students as people until they're adults.
And so, they go through school, and we force them to do hours and hours of homework (because how will they learn otherwise? What, you expect the teacher to teach instead of the student teaching themselves?), some of them have jobs, a lot of them have extracurriculars because we've told them that they have to get into a "good" college (IvyLeague or adjacent, anything expensive, really), and that means they need extracurriculars in order to show they're well-rounded.
And then they get home, and their parent says "it's my time with the toy, and I'm going to do whatever I want with it" and that could mean forcing them to do work or childcare or ignoring them. And of course, this isn't a person, so I don't have to pay them for any labor at all, if I want my teenager to watch their younger siblings, well that's their job as my toy, that's why I got it, I don't have to pay it.
And then, they're told to go to bed. And that's when they are no longer expected to have to be a toy for everyone else, and they take that time to be a person (quietly, so as not to bother anyone else or they'll get in trouble), and as soon as someone finds out that the toy is trying to be a person, they get into trouble, because it's supposed to be a toy that does what I tell it, not a person yet.
And then, of course, they turn 18 or go off to college or whatever, and all of a sudden, they must be a person with all that entails, when they have been treated like a toy, but the transition should be easy for them, why are they acting like it's hard?
