Yes... twice... and I did say it about a dozen times but I probably said it softer than the "Mistress" portion because I was never confident about not screwing up. As for being "chicken", I just believe discretion is the better part of valor and the better part of valor is avoiding a massive beating for saying your name as if it rhymes with "pain" rather than "mine".
And, your favorite moment of the session was completely based on my fear of doing it again. When you asked if I could talk, I just panicked and nodded yes instead of answering out loud. That was completely to avoid possibly screwing up the pronunciation again rather than not actually being able to articulate an answer.
Y'know... I have access to a real dungeon in Detroit...
