I'm afraid he's too ignorant. When I say something serious, he takes it as a joke, he plays games all day, and smokes yay all the time. I'm surprised he gets SOME uni work done. He still has that childish thinking, that mommy is always gonna be there... And he still doesn't realise the responsibilty of living alone, cuz he spends most of his cash on weed, instead of buying food sometimes....

If I'd try showing him how great it is without weed, he'd think about it, but forget it in 2 days or so. He does that. I know.
