To think that a child shouldn't talk to his DM in that way?

[Gide]

Just come back from drinks for a friend's birthday. All was well until the DC18 came home. He immediately started telling his DM that she's a bitch, a c word, sat with us all and kept telling her this. She did not remonstrate with him.

It was a noisy room, another friend and I were messaging back and forth with (everyone was on their phone, there was a running joke about setting someone up with a friend, we were Facebook stalking him). I was very uncomfortable with the way he was speaking and it was late, so I left (stayed sober cos I wanted to be able to go when I felt like it and not rely on others)

AIBU to be uncomfortable? My only other close friend with a DC that age has the most amazing relationship with her DC, who is a polite and lovely young man.

Was he drunk? Not an excuse but a possible explanation

Oh and calling him a little fucker for calling his mum a bitch and cunt is rather hypocritical wouldnt you say?

No not really hypocritical at all. I'd never call my mother either of those words "just for effect". I wouldn't call anyone those words just for effect honestly.
But if one of my friends had a son that walked in the door on her birthday and called her a cunt, I most certainly would belt them. And call them a little fucker too. I have no tolerance for such abhorrent behavior or abuse to someone who loves them unconditionally. And if she wouldn't stand up for herself I would. Someone has to.

So he could have "punished" her when the friends all left? Or he could have told her that he was right since not one of her so called friends disagreed with him and had his nasty bullying reinforced.

I really can't imagine not saying something in that situationz

i know someone who brought their son up to be foul mouthed from a very young age. in fact some of the first words he said was cunt, fuck off bastard.
his mother thought it was hillarious especially when when this little angel would swear at me people in the street or in shops "what you fucking looking at cunt" , telling his pensioner neighbour to fuck off, she'd laugh and say hes only joking
hes 13 now and hes quite often telling his mother to fuck off calling her a fat cunt, she doesnt laugh about it anymore i do
just saying......

18 isnt a child, her child but not a child
