I normally greet my Mistress with a good morning Maam, and in the afternoon after work with a hello Maam type thing. Other than that she has made it real easy for me. As long as it's done with respect and endearment I can call her whatever. I found out "ole lady" isn't exceptable but honey or dearest and the such hasn't gotten me into any trouble yet! I'm sure for some the title is very important and I respect that. For us it's just show respect at all times and know your place in life.
