This situation is real. I've had the same doctor my entire adult life (~25 years). We've got a pretty informal relationship. I even saw her hammered at a bar one night, and had to give her a ride home because her friends were also drunk AF. Anyway, a few years ago, during an annual checkup, she asked how my family was doing and I made a joke about my brother drinking too much. A few weeks later I started receiving pamphlets in the mail about treating alcoholism, ads for rehab centers. I just brushed it off, didn't make any connection. Then, the next year, during my annual checkup, my doctor wasn't available, so I got a different doctor, someone I'd never talked to in my life. She immediately started asking me about my drinking. I fired back, asking WTF she was talking about. She said, "Oh, well your file says alcoholism runs in your family.", and then started lecturing me about getting over the shame of alcoholism is the first step to beating it. I don't even drink. No one in my family drinks other than my brother. He was drinking a lot at that time because he favorite NFL team (LA Rams) was doing really well, and he was celebrating a lot. And it was just a joke.

The next year, during my annual checkup, I gave my doctor a load of crap, telling her to record nothing I say unless I explicitly tell her to. She tried to defend the system, but she agreed. I'm still upset that my "file" still mentions alcoholism.
