I'd like to give a current personal example, but as many of you are aware, I am committed not to betray confidences or information about people I know. Maybe it is enough to suggest that you can fill in your own blanks of times you have wrongly judged.
It often happens when in hearing a story from a friend, I take up her side and make up the story of the person that she says has wronged her. Bad enough, but in the case I'm working with now, I didn't even hear that my friend was wronged. I made that up, too!!!
Again I am reminded of my mother's words when I told her about a situation I had heard about. "Well, I don't know anything about that." End of conversation.
