I was at an AA meeting once, years ago, giving my lead. And while I was talking, a guy who'd come in clearly drunk got up and left, literally weaving his way out the door. He weaved his way over to his car, walking past a group of smokers outside, got in it, backed directly into MY car, then drove off. I didn't find out about the incident or the damage to my car until the meeting was over.
The interesting thing is that no one thought to stop this guy, even the people who watched him hit my car and then drive off. I guess they were so used to seeing, and dismissing the man (who was a chronic relapser, often showing up drunk) that he was basically invisible.
So I called the police. He had made it home safely, thank God but it might not have been that way, and I do think that we need to remember that our responsibilities as citizens aren't suspended at recovery meetings.
