I know we’ve had this discussion before, and I said that I wish we had one title for women like men. I was told we do - Ms, but I’m not that fond of it. To me it says left on the shelf female, but I’ll no doubt be told that that is my own prejudice !! It’s actually from having older, unmarried teachers at school.
However, I am going to use it on unofficial things like my Tesco and Next account to change my own attitude.
