And you followed through on talking to the father? As we all know, that’s the only solution for some! Others couldn’t care less as the parents aren’t going to do anything anyway!
Yes, I did speak to his father - who is a decent man trying to raise decent kids and for the most part succeeding (even this kid really isn’t doing anything seriously problematic - it’s just that if he’s not pulled up now, it’s likely to get worse and worse).
The boy has been very polite to me on the couple of occasions I’ve seen him since.
