From what I have read, apparently it is healthier for children to witness their parent drinking sensibly (occasionally having one or two glasses socially then stopping, but not every day) than it is for them to grow up with the parents completely abstaining. Or with, obviously, an alcoholic parent.
I am an alcoholic. But I don't drink. But I miss the social part. And drinking a bunch of beers while smoking a bunch of cigarettes. Partying, swimming, boating, laughing, getting in trouble. Shoot, it's enough to make me want to relapse. ... Nah!
When I first got into Recovery, I also realized how evil alcohol is. After a while though, that kind of wore off.
