It's difficult fo anyone here to judge, as we weren't present. It is quite possible that the Lady-in-waiting was just making conversation and was genuinely interested in where this person came from - i.e. her background, her life-story, her heritage. Or she could have been 'superior' or condescending, or somewhat aggressive or patronising. I suspect the former rather than the latter. But nowadays there's a lot of suspicion and mistrust about, and people take offence readily - not surprising in view of the online abuse that flies around all the time.
