You’re right, but you’re also being an asshole. In the same way that discipline is necessary, rebellion is necessary and space is necessary, it is a balance. Neither extreme to either side will be effective.

Teenagers will, and should test the rules.

The parent cannot ignore that, but simultaneously, punishing every little thing will severely affect emotional development.

Similarly not everyone is able to fit into your standard of discipline, such as myself. Trying to enforce it in that case, is foolish, and ranges from simply ineffective to highly destructive. In that element, you must find a way to work with that, and to best allow the individual to grow, even if it isn’t in the way that you expected or wanted.

If you ever become a manager or parent, you probably won’t be too well liked for that. And unless everyone you manage, or your kid fall into that then you’re kind of an idiot.

This is the problem with JP who it seems you probably follow. His advice is great for a certain type and person, you might be that type of person, and if his advice works for you that’s great. (Though you also don’t seem to be capturing its full extent, or even understanding it properly, I would make sure you seriously read up)

But for some people like myself, his advice is laughably ineffectual. I don’t clean my room or do the dishes, as an adult, unless I must. Why, because I have far more important things to worry about. If my room is messy, and the dishes are piling up in the sink, I still have work to do, and neither of those things affect it.

So use some empathy, don’t expect your sisters to grow up instantly, or even try to push it. They will grow up, probably with some flaws, in the same way as everybody else. They’re only teenagers, the only people who expect teenagers to be grown up, are fools and the military.

The brain isn’t fully developed until 25. Even with most of a Ph.D. my brain is apparently not fully developed.
