Do you teach your kids to address adults with Ms. and their first name or their last or what?

I was discussig this with a southern friend of mine. She introduces her adult friends as Miss Jane rather than Ms. Doe to her children. Usually I say, “you can just call me Leslie” but many parents think it is a lack of respect to call an adult by their first name, BUT I think it sounds very weird to be called Miss Leslie, because I am from the NE and we do not use that. I tend to think that the sign of respect is to address people as they want to be addressed. I ask people, especially people senior to me, do you prefer I call you Ms. Doe or Jane, and they can let me know. I don’t insist on calling them what I think is respectful. I should say that generally I think when in Rome do as the Romans, so I don’t go around saying, “don’t call me Miss Leslie, because I also do not feel it is my place to contradict the mom of a young child.
