You barely ever had to deal with pubescent children? :-)

I raised kids. Never had to deal with anything like what is described. Sounds like someone read some questionable books on parenting, unfortunately followed the bad advice in those books and this is the result.

And this entire thing is about bad parenting. Its always easier to just give the kid a tablet and go back to whatever you were doing. Its always better to actually interact with the kid. That trade-off of time is important because if you mess up when they are young, you spend a lot more time handling issues later on. That time you gained by giving them a tablet will get payed back someday, usually with interest. That's what is happening here.

I mean, that's really not normal puberty stuff, but... okay.
