My wife would say I leave out important details. I would say she sometimes takes 10 minutes to relate 1 minute worth of information. I skim when she goes on and on (like I do when I read anything longer than a picture book), and she makes up details to fill in my gaps.
OTOH, when I do this, it’s because I don’t quite remember the details as I’m speaking, and am hoping there’s enough information that you can intuit who I mean. You can tell because, if you stop to ask, I’ll have to pause and think for a bit. Heck, likely, I’ll have to describe characteristics about the person, since I will have completely forgotten their name.
My friends generally do figure out who I mean, so the conversations work more quickly without getting bogged down due to my deficit in remembering names and instant recall of details.
And it seems to run in the family, BTW. My dad does it really, really badly, to the point that we actually do often not know what he’s talking about. Mom forgets a whole lot less, but uses this strategy when it happens. Only my sister seems to be able to on the fly change how she says something based on what she remembers. (This is why she is the multilingual one–if she lacks the word for one thing, she instantantly thinks of another way to say it. So she’s functional on a lower vocabulary.)
