"Dad, I forgot to buy you a newspaper."
"I have no son."
Then I would laugh, feel better, and remember to buy a paper next time. Or maybe two copies of the same edition, as atonement.
If you get that my dad's response was a joke, consider yourself lucky. I've met people who don't recognize when someone's ridiculously imitating a negative emotion, and they seem sad and unfulfilling. Fortunately, they also avoid me, because I constantly falsely display negative emotions ridiculously. I prescribe lots of episodes of Mama's Family.
If I identify that someone's afraid of me or someone else in the room displaying a negative emotion Deliberately doing a bad job at pretending to believe that I have superior social value and quality makes me laugh, and self-selects the people who don't get the joke to avoid me. also I believe that many people who can't spot the difference between a pompous ass and a parody of a pompous ass are themselves pompous asses, and so some of them self-select to avoid me. Win-win.
