Writing a card to an old ante-natal friend who's moved away and I only see once or twice a year. This summer she told me her teenage daughter, Natalie had decided she was non-binary, tending towards male and from henceforth wanted be known as Boris or he or they (all names changed). I know that mum and dad and other son were not very happy about the whole thing (thought still trying to be supportive parents) and it has been hard for them as a family to come to terms with. We don't really keep in regular phone or email contact, so I don't know if there have been any developments since. Do I write to 'Chas, Dave, Boris and Freddie' or 'Chas and Dave and family'? We're seeing them in the new year, so I don't want to just not write a card....and still have to eventually call Natalie/Boris by some name....
