On the flip side I think a lot of parents do this to themselves. Kids are not born knowing how to be polite, respectful, play well with others, etc, it has to be trained. It is an exhausting thing to train but it pays dividends. Ironically the less effort you spend on this the worse your kids get, making it even more of a misery to parent them.

Of course there are exceptions (I don't know if you were being serious/clinical with ADHD but that's one of them)
