First names. I call her Carole. She calls me Bob. I'm around 15 years older than she is and that has something to do with it. It's no big deal at all. We're both far too into what we're doing to care about things like that. She has a Ph.D. I have fifty years of reading about depth psychology and living in a world oriented to that kind of thing. We're equals and comfortable with it. Take care.
