Idk. If someone told me I'm alone with a British person, i wouldn't read an implicit feeling of discomfort. I would say, "idk, I think you're supposed to offer them tea"
I'm alone with an Australian. "Are they hot?" "Are you asking for advice on flirting?"
I'm alone with a Russian. "Do you feel safe? Intimidated?"
I'm a human with experiences that make these statements feel like they have implications, but a machine should give the same answer regardless.
