A town in France has got rid of the term 'mademoiselle' and from now on, every woman is to be 'madame'. Not that big a deal, but might be a bit weird to refer to a 7 year old girl as 'Madame Brochard' or whatever.
Increasingly, the use of personal titles that indicate gender are on the decline...because nobody wants to be a chick...because people don't want to be pre-judged based on their gender or they're one of these weird trannies that doesn't know what it is.
If you think this level of mystery is a pain in the arse in business dealings and that you don't really care what gender they are, you just want to know so you can address them properly. Here is a handy pro-tip to guide you through the mire of this nonsensical identity hiding bullshit.
