Dear parent asking this question:
There is no “curing” the teenage brain. Teenagers, and children in general, were sent here to be our replacements. Therefore, as their brains are getting into shape, ours are decomposting, as it were. So unfortunately, it is hard to judge and gauge them because for every ridiculous thing they do -pierce their cheekbones, drink 16 beers in a row- they actually have the excuse “my brain is still developing”. Similarly, when we forget the name of that band we worshiped in high school, or that we had a therapy appointment yesterday at 4pm, we too can say “i’m getting older.” So- my advice to you, noble parent, is that you ignore as much as you possibly can- and remember, you only have three real responsibilities– to feed, clothe them and put roof over head.
Regard everything else -hugs, laughs, movies, allowance- as special benefits and privileges to be dispensed or not at your discretion.
I won’t bore you with details of my no frills upbringing in Estonia- but it entailed lots of cleaning sheep ship and no video games.
Wine helps, as does sleepaway camp.
