Now, see, Amber... You asked about something that shouldn't really matter (the "official" (my word) protocol for addressing a Dom that's not your Dom), and all this maelstrom erupted. But now, out of that, you get to meet someone you didn't plan to meet, spend a bit of time with them, and expand your world in what will most likely be a favorable way.
Everything "happens" for a reason, I believe.
Somehow, I suspect that the original meeting wasn't about the original meeting, although none of us knew that at the time...
Have a wonderful weekend.
