Joe: Greetings.
Jane: Salutations.
Joe: I extended a greeting.
Jane: I know. I just acknowledged it.
Joe: I’m aware you took note of it.
Jane: Can you be certain though?
Joe: I’m certain that I’m not certain.
Jane: Your confidence in your lack of confidence doesn’t persuade me.
Joe: Understood. Goodbye forever then.
Jane: Goodbye forever.
