Yeah, and memories can change over time, especially if you've been telling a particular story over and over for decades. It's human nature to start unconsciously embellishing things to make for a better story. From what I understand, Nichelle Nichols' famous MLK story has evolved over the decades from her thinking to herself, "What would Dr. King say?" to her getting a phone call from MLK, to her meeting MLK at some event where he talks her out of leaving TOS. George Takei remembers some cut lines in an unrelated scene in TWOK as "Sulu's promotion scene" and thinks that William Shatner intentionally gave flat line readings to sabotage Sulu's big moment, when in reality, Shatner was likely just playing Kirk's depression at the beginning of the movie. But good luck convincing Takei of that at this point.There’s nothing nefarious about a 50-year-old memory. My memory plays tricks on me about things less than a decade ago. It’s one of the reasons why the police interrogate people immediately. Over the course of hours your memory can change how things went down.
I commonly interview people about stuff they did 20 to 30 years ago in my freelance writing career, and people's memories can vary a lot. Some folks are as sharp as ever and can recall all sorts of details, and some people only vaguely remember the circumstances, or conflate two different things that happened years apart. That's when you have to do research to confirm the facts of the situation as best you can.
