I met somebody once (not Erin), who just could not be wrong or take accountability or blame for anything. It wasn't a choice, it was the way their rigid mind worked.
For example, this person told me that snakes were not in a particular suburb where they lived and when I found recent news articles about people seeing snakes in that area, with photos of the snakes and snake catcher warnings, they couldn't deny it, but they still couldn't accept it could happen at their property even though it was in a 1km vicinity, so came up with all sorts of irrational explanations about why I'm wrong and why that information doesn't apply to them.
Then when I actually saw a snake at the exact location this person lived and they put it in a bucket to examine after originally denying it was a snake, and saying it was a lizard, they said it must have been transported from a different place because the neighbour had an excavation business and he must have inadvertently transported the snake from a work site 400kms away.
It was crazy stuff.
I wonder if this is what Erin does in her mind. IMO
