Me and my friend got into a fight because of how my other friend’s wife described her job?

So my friend has a wife that was an STNA, she ended up dropping out of school and is no longer in that field. I have another friend, who is a doctor currently and we were talking tonight about the other friends wife, and how we like her because she can be a bit abrasive and hard to get along with. I get along with her pretty well, but he does not like her. She can be very socially awkward.

In particular he doesn’t like that when meeting them, she said she was a nurse. He said that it’s dangerous to say she is a nurse because she isn’t a nurse, she is an STNA, and I said “it’s not dangerous if you are just at a party and you don’t want to have to explain what an STNA is, and for me, that would basically be the same thing as a nurse for the sake of getting to know someone.” And he just kept saying she was a liar and that she isn’t a nurse. And I just kept explaining that she probably doesn’t want to have to explain what she is, and a generic “nurse” covers it for 90% of people, understanding that for someone in the medical field, they would know the difference.

He ended up getting really angry at me because of this and I am now just confused if I was being unreasonable? They were just meeting each other, and he asked what she does and she said a nurse. Which for a social meeting should be fine for most people, since she isn’t trying to pass along medical information or trying to diagnose anything…. i just feel like I’m going crazy

I get being frustrated about it but this was years ago that she said she was a “nurse” and it just doesn’t matter. She was introducing herself to him, she asked what she does and she said nurse, because she is socially awkward and probably doesn’t want to get into what an STNA is for people that doesn’t know, I know an STNA is different from a nurse, but most people just won’t know or care…
