I hate when someone says something that's incorrect, and when you correct them they say, "Are you calling me a liar?"
Most of the time the person asked that question becomes apologetic and says, "Oh no..."
Instead, I just say, "No, I'm calling you misinformed. But if you choose to propagate this misinformation further now that you know it's incorrect, then you will be a liar."
Ha Ha! You and I would make a great tag team at parties, talk about Mr. Popularity.
