YOU SAID:
i'm at your mothers house
INTO JAPANESE
私はあなたの母親の家にいます
BACK INTO ENGLISH
I am at your mother's house
INTO JAPANESE
私はあなたのお母さんの家にいます
BACK INTO ENGLISH
I'm at your mom's house
INTO JAPANESE
私はあなたのお母さんの家にいます
BACK INTO ENGLISH
I'm at your mom's house
That didn't even make that much sense in English.
