Funny about the Uncle/Aunt thing. I found out some years ago, that my grandparents were in a quad with another M/F couple when I was a kid. They spent a lot of time with us, holidays, birthdays, etc. I called them Aunt and Uncle. I think if I was in a relationship with someone or others who had kids, I'd prefer they called me by my name.
