I'm a Ms, cos I'm not married and am far too old to be a Miss.
I remember the day I made the decision to be a Ms. Was in the late 80s, I was a teenager and my dad, who worked for a bank, told me that they were recruiting, and that any CVs that had 'Ms' on them were automatically binned. I was and decided then I was a) going to be a Ms and b) was never going to work in a bank. Oh and I didn't speak to him for the rest of the day
