Have you ever known anyone personally that writes life stories & gets things wrong about every other paragraph?

I have a sister that posts long stories on Facebook. She reposted something she wrote a couple years ago about young life on the farm. She made 6 major errors including attributing some things that happened to me or my sister to herself. Claims she was in 1st grade when JFK died, I remember sitting in 1st grade myself & having our teacher tell us & the whole classroom crying. She wasn’t even in school yet. This same sister has been writing a book about life & the family and has said she will publish it.
