DS glued to the poxy thing. He is 15 a good boy. Does go out and see mates so sociable. Does not bring me amy trouble. Studies hard at school. Somim very lucky. But when he is on that thing, I call it 'the machine'. He plays GTA with mates and all you can hear is him shouting out ya mother fucker" or fucking get ouuut my way or oi you ya silly prick etc etc.
I have spoken to my friends about this and work colleagues and they say their sons are the same 
Would point out does not act like this when not on play station.
AIBU in wanting to launch the fucking thing out the window or accidentally on purpose cut the wires. He has been on GTA for about a year. Drives me nuts. And when I go flying in his bedroom to tell him off he goes mad shouting at me. As I said only behaves like this when on that poxy 'machine'
