Oops...forgot to mention that I used to work with a Barbara Jane once and she, too, went by her initials. I had a real hard time divining why a beautiful woman would choose to adopt those initials for her name. It was very hard to keep a straight face when talking to her.
A co-worker of mine has a beautiful little 3 year old named Mary Jane.
I don’t know her all that well to ask her: “WHAT were you thinking?”
But I’m old. My co-worker is young. It may never have even occured to her what that refers to. And so what? Mary Jane is a beautiful name. Why let its connotations with marijuana stop you from naming your child that?
