@excuseforfights - he's still an entitled brat, and actually worse than he was at the age of 7. His parents have never disciplined him, have spoilt him to the extent that he expressed a vague interest in horses once - so they bought him one (which he, of course, then being 12 lost interest in very quickly, so now his mother's doing all the care for)... and although he has learned to be polite to me (it took maybe another six months or so, of my correcting him about calling me by my first name, because he'd assumed he could do so), he still has an air of being better than others. It's odd, because none of my son's other friends are anything like that - and have spent most of their lives, pre-Covid, wandering freely in and out of my home, eating with us (bottomless pits, all of them!), and generally showing that their parents raised them properly. "Bob" is the only spoiled one, the only one whose parents can't bear to hear anything bad about (they were highly offended that a teacher had dared to suggest that he might need some help with his math, a few years ago, because "Bob" was, of course, good at everything...), and the only one who I suspect may have a nasty shock ahead of him when he enters the real world of adulting.
His younger brother is much the same. Blacked my son's eye one day at school, by (and I'm quoting a teacher who witnessed it, here) deliberately swinging a metal lunchbox into his face. The mother's response? "Oh, well [my son] ought not to have been in the way of it!". I completely get that accidents happen - but when a teacher uses the words "deliberately swung", it obviously wasn't an accident. His punishment, according to another mutual friend, was a trip to the cinema, because he'd had such a tough day. My son's evening? Spent in pain as the swelling filled in, and a trip to A&E to check his nose wasn't broken.
So, it might have been 9 years, but... no. Also, I was one of the last of our group of "school gate friends" to ban him from my home, and one of the last whom he was rude to, or offended.
It's not "Bob" or his younger brother's fault, per se. It's because they've both been raised as Little Princes who can do no wrong, ever. I blame their parents. Which is a shame, because otherwise their mother's really nice, and I used to work with their father. Until it comes to their sons, they're both level-headed and lovely. The total opposite of their boys
