And. To make this more than a GIP -
I met a black belt today. In Pakua, we call all black belts "Master", regardless of sex. This one's name was Dominique. She usually works with kids, and they use a shorter form of her name. We could, too.
"You can call me Master Dom."
I could tell by the way she said it that she had *no idea* it could be anything more than, say, Master Deb.
I, of course, did not laugh. I very much did not laugh.
