Most of my kids’ friends called me by my first name from way back, others always called me Mrs. (Usually wrong last name). I corrected to the correct last name and Ms. But as they got older, I just started saying, "Please call me “First Name.” I remember at some point one of my aunts suggested I just call her by her first name instead of Aunt First Name. To me calling her Aunt, wasn’t distancing, it was acknowledging a family relationship.
