My nephew has this ability (or disability). He is an unusual person. Long winded answers when you ask a basic question. Pretty soon you stop asking him questions because he’s so annoying with his long drawn out answers. Succinct will never be an adjective used to describe him.
However, I have miniature version of this “ability”. Life events work like a calendar for me. I think because when I had kids, to keep our activities straight, it was always on a calendar. It’s much more generalized than the examples in the article, but generally helps me remember what was going on at one time or another.
My wife can tend to long winded answers—but I figured out how to get her to slow down and organize her thoughts.
My rule—no pronouns. She must give the first and last name of any person she is discussing—every time she mentions their name.
It works.
