YOU SAID:
I've been here before. Your dad was drunk.
INTO JAPANESE
私はここまでしてきた。あなたのお父さんは、酔っていた。
BACK INTO ENGLISH
I've been here ago. Your dad was drunk.
INTO JAPANESE
私は前にここでしてきた。あなたのお父さんは、酔っていた。
BACK INTO ENGLISH
I've been here ago. Your dad was drunk.
That didn't even make that much sense in English.
