YOU SAID:
I do not know that there are things I may know
INTO JAPANESE
私は私が知っているかもしれないものがあることを知りません
BACK INTO ENGLISH
I do not know that there are things that I might know
INTO JAPANESE
私は私が知っているかもしれないものがあることを知りません
BACK INTO ENGLISH
I do not know that there are things that I might know
That didn't even make that much sense in English.
