Kids are people. People have feelings.
Good parenting consistently is hard, very hard and sometimes basically impossible, but the difference between parents who at least try hard to raise kids well and those who sort of gave up on their kids is striking (tiktok and other digital stuff is a good yardstick of overall state of this, when I see kids of other folks using it and clearly addicted I am losing all respect for those folks as parents, and its always a big bag of various failures and neglect coming along). Its heartbreaking to experience, especially the powerlessness.
