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.
I think for dealing with someone you’re close to, that’s a great option.
I don’t see this nephew very often, and when I do, I tend to avoid him.
I will pass on your suggestion to my sister and BIL who do have to interact with him on a nearly daily basis.
I should try that with my wife. She can tell a story involving 5 women and the whole thing is one long, “She told her that she didn’t like it when she did that, but she was standing there and she made a face and did that thing that annoys her, so she jumped and let her have it.”
