YOU SAID:
my mom is my dad and my dad is my mom
INTO JAPANESE
私の母は私の父であり、私の父は私の母です
BACK INTO ENGLISH
My mother is my father and my father is my mother
INTO JAPANESE
私の母は私の父であり、私の父は私の母です
BACK INTO ENGLISH
My mother is my father and my father is my mother
That didn't even make that much sense in English.
