She doesn't sound like a native English speaker
, therefore she has an accent.
I never said her accent sounded like an Eastern European
english is the native language in several parts of the globe, and perhaps you don't know such things, but it does sound different, despite it's native or at least official language for all these people
i've lived for a few months in UK and heard any sort of english, all by native speakers, even born in england
tbh, she speaks like a very good continental european english speaker and it's too generic to even be called an accent
what you said sounded derogatory to me.
