Umm, what's the different between Miss and Lady? Why Yuri so concern about that title? Does the 'Miss' one means there relationship closer than 'Lady'?
Sorry if my question sound silly, I'm not good in english.
@Ammaple27 You just answered your own question.
'Lady' is used to talk to superiors. 'Miss' is also respectful but more on the same level on the social ladder and used between peers.
