Well he got brought home by his friend's mum after throwing up all over her house. He couldn't walk or talk. 
He's 16 so driving isn't a consideration but it did mean he had to walk 1.5miles with a bunch of flowers the next day to appologise. He's never been drunk before and it wasn't pretty. He's still nursing injuries from falling over. I hope he learns a lesson.
At least your dd thinks about being over the limit. That's a good thing.
