GOOD QUESTION!!!--
First of all, Mel, You've made my day....
I think it's really quite mysterious why we call them by their first names, it's kind of "tribal," not anything anyone of us can change....
It's LIKE SAYING "Serenade" INSTEAD OF "SERENAHHD' -- AS IN "he sang her a serenade last evening, playing on the guitar, the whole rigmarole, like it was 19th century Italy" --
Arlene Croce led a small crusade to get pople to call the ballet serenade instead of "serenahhd," and about 3 people picked it up; I tried for a few days, but I couldn't keep it up.
It's like the things teen-aged girls wear to take class-- in Suki Schorer's day, they all wore rubber baby panties over their tights, GOd knows why... now it's those cute knit shorts (at least at BBT, where the teenagers take class with the rest of us on Saturdays -- these fashions are almost impossible to go against, God alone knows why.....)
When I write for publication, I say Farrell -- but when I'm talking about her, or thinking about her, I call her Suzane -- Once at a Question and Answer session where she was the guest, i actually called her that by accident in front of everybody ("this question is for Suzanne" -- I wasn't thinking about how to present myself, I was just trying to phrase the question.... later, when she was answering someone ELSE's questino, I realizd what I'd done and was really mortified.....
Maybe it's like with Christians, who call the son of God "Jesus," and his mother "Mary" -- maybe that's how much they mean to us.....
