He also says he cannot write in Polish (so can he read it?).
Yes, that struck me as odd. My darling husband started me off on the right road very shortly after we met. In typical, brusque, brisk, blunt and ruthlessly efficient Polish style he told me that he didn't have the patience to keep telling me how such-and-such a word was pronounced but that as Polish was a phonetic language, he would teach me the alphabet. Then I could read any word and pronounce it properly. He also told me that the stress was usually on the second last syllable so what more did I need to know. The grammar? Don't worry he told me, you'll
never learn that!
Anyway it was the best thing he could have done. The phonetics of the Polish alphabet are really easy though I think maybe the fact that I was already used to teaching English phonics to children was a help. I think it only took a weekend to learn the alphabet and then I was independent in terms of teaching myself words.
It is best not to eat any cakes, be it British or Polish, unless you are a slim person.
A little bit of everything in moderation is ok I think.
