I have a family member who will drink too much at family celebrations and then get on his bike or in his car and go out. He is not married nor young, but this is not an excuse for driving in this state. Everyone always worries and there is usually an argument as people try to stop him. He does not listen and goes anyway. The worst part is that he does not come home sometimes for several days. No-one knows whether he is dead or alive until he turns up. How do you get through to someone like this?
