Yep, you make good points. I think the problem I have is that if I stay away from drinkers, I'd never see any of my family and friends. There seems to me to be a fine line between "normal" and "problem" drinking. I lept across that line quickly and decisively a long time ago. I just wonder whether some people shuffle over the line slowly over time? And if so, if we see someone getting too close, is there anything we can do?
But like you said in your first post, I don't understand normal drinkers. Maybe they always stay on the right side of the line. I hope so.
