I use to have a beer or glass of wine especially when going out to dinner or to the bars when I was much younger. Now I can go months without having a drink. It is not for any particular reason. I just do not think about it. Or maybe it is because my mother was an alcoholic and I saw how it could wreck havoc.
When I was in San Francisco my landlords gave me a bottle of champagne. I never opened it. We have wine in our cupboard. I never think to open it. I am not against alcohol, I just do not imbibe much.
