Another Pattern

"I don't drink much, but I learned from my father to drink a little before bed, and I don't think there's anything wrong with that, because I never drink much, and there's nothing wrong with that." (Always a run-on sentence when she's feeling defensive. SHE brings this topic up, not me.)
"I know, Grandma."
"And I only drink this much." Fingers out about 1 inch apart. (Right.)
"Uh-huh."
"And I don't think there's anything wrong with that. I learned that from my father. He was told by a doctor to drink wine before bed, and so I learned to drink wine to put me to sleep from my father."
"Ok, Grandma."

We have had this conversation, verbatim, about 9 times in the last 4 days. I have never said a word about her drinking, although it is excessive. I found one of the enormous wine jugs this morning and dumped all but half a glass out... She complained last night that she didn't fall asleep from the wine she drank (an entire bottle). Probably because it was half water, courtesy of me.
