I'm a few years older and now I do correct myself if I ever call someone a girl who is a woman and I pull people up on it sometimes too.
I'm not a girl, because I am a grown up.
I am a woman.
Which shouldn't need pre fixing either. I'm not a young woman, a single woman, an older woman, an attractive woman, etc. It shouldn't needed prefixing.
Unless in a conversation regarding trans issues it shouldn't need pre fixing with 'cis' either
When children write stories they write in the style of the words they hear and the words they read.
They write "the man went to bed"
But they write "the beautiful young woman went to bed"
Fuck that. I want a female equivalent of man that needs no further explanation.
No doctor 'a young woman presented today' or 'a pregnant girl presented today'
These are just women. If the age is relevant then why not state it as a medical fact?
A 25 year old woman. That's the only kind of pre fix I'm happy with from a medical professional.
You would be amazed how many times my medical notes have this kind of woolly language in them. But these are not children writing a book report, the language matters. Because when they infantilise you they also don't pay proper attention to your medical problems.
