Certain accents. She can be gorgeous and all, but some accents are an immediate turnoff for me…
I’m German. Foreign accents (I.e. some foreigner speaking German) are either funny or cute to me. If I feel neither, that’s probably because I need to concentrate to understand. In German accents, a Bavarian accent, a Saxon or a Frisian one turn me off.
In (to me) foreign languages, I don’t care, meaning that I’m just as fine with „Oi com frum Birmingham“ as with a posh Oxford accent. Also the southern French accent is fine with me, as well as the northwestern one. I’m also fine with Breton, but that’s a language, not an accent. And I don’t understand the latter very well anyway, let alone speak fluently.
The ones associated with poverty are the usual ones that catch crap. Regional or recent immigrant.
Maybe this person is going to surprise me and just finds Australian or Parisian French grating personally, though.
