I've often said that even when sober, the reality, the world, that exists around the alcoholic, can be very sick, delusional, and so on. I have seen my wife -- when not drinking or drunk -- tell me about something that happened the night before which isn't even close to anything true. Very sick and very sad.
I used to say this was one of the 'ism's -- the rage, anger, hatred, lying, and so on. Sometimes, it's very odd behavior.
I have found that even when sober -- logic is not part of their world. It's very sad.
