That wasn't throwing you under the bus...
It's amazing how vested some people are in never admitting they made a mistake. I had an exhausting conversation at work because one person said something in frustration. When they were called on it, rather than just saying "I said this, but didn't mean it" the person is doubling down on claiming they never said it to begin with and I am lying about what they said.
It's exhausting and I don't understand the end game. Both of us know the person said it. Sure, it's he said / she said everywhere else but they need me to get their job done and now they're burning that bridge. And for what? Like I said, simply saying "I didn't mean this" is easy. And there really isn't any practical consequence to that.
