I'm stupid, I started reading the subtitles for when the polish started and only 30 seconds later realised that I in fact do speak and understand polish fluently,(reply>), Been there. In English, in fact.,(reply>), My half brother does the same with Greek, even when people speak Greek to him he replies in English and won't start speaking Greek until he remembers to. He moved with my mum back to England when he was 3 ,he was born in Greece and his dad's Greek.,(reply>), Same,(reply>), @CL It's constantly happening to me with Tom's videos about Germany,(reply>), @Atanaa how unexpected is it really? Title says Poland, he says he's in Warsaw and that he's with a Polish speaking team
