I never (or very rarely) say those things. I’m generally kind across the board. I even think kind things, most of the time.
But sometimes I play a game in my head, “What if…” What if I just said whatever I was thinking? For instance, while reading blogs I occasionally come across one that is just so random and makes no sense whatsoever and I wonder, what if I were “that” mean person and I wrote in the comments,
“Hi. I totally have no idea what you are trying to say.”
But I don’t. And I doubt I ever would, unless my frontal lobe were injured or something.
