YOU SAID:
I don't know what is being said
INTO JAPANESE
私は何を言われているとは知らない
BACK INTO ENGLISH
And I said what you don't know
INTO JAPANESE
私は知らないと述べた
BACK INTO ENGLISH
He said I don't know
INTO JAPANESE
私は知らないと述べた
BACK INTO ENGLISH
He said I don't know
That didn't even make that much sense in English.
