I also think that most people are "normal" drinkers because they rarely, if ever, negotiate with alcohol. They have a drink or two at a function or split a nice bottle of wine with an amazing dinner every once in a while and really don't think much about drinking at all. They might even get hammered at a bachelor party...but they have a normal hangover instead of shaky horrible withdrawal and don't do that again for months, years or ever.
It doesn't control them at all, and they don't have to control their drinking at all.
It continues to amaze me how the majority of people are like this instead of like us alkies. When we drank we thought EVERYONE was a huge drinker, that drink was the focus of every gathering to everyone. No, that's not the case at all.
