That was the thing that confused me so much, the monologue that would have a story that would just start all over again, almost word-for-word, sometimes 3 times. Late night phone calls that would go like this every once in a while. Only later did I figure out this was common with alcoholism.
I guess because alcohol literally burns holes in the brain eventually some circuits are going to get crossed and the brain will just stop working normally. Awful.
