YOU SAID:
I’m going to do your mother
INTO JAPANESE
私はあなたのお母さんをするつもりです
BACK INTO ENGLISH
i am going to be your mother
INTO JAPANESE
私はあなたの母親になります
BACK INTO ENGLISH
i will be your mother
INTO JAPANESE
私はあなたの母親になります
BACK INTO ENGLISH
i will be your mother
That didn't even make that much sense in English.
