Ah yeah my mom does this. She's in her early 70s and she's in very good health and all, but she'll say things happened that didn't or she will remember things completely wrong.
Like recently she was telling me she watched "that movie you recommended," and I was like what movie, I didn't recommend any movie. She absolutely insisted I did and she even became angry, insisting that yes, yes you DID recommend that movie and it was terrible.
I just shrugged and was like okay well sorry you didn't like it, whatever it was.
