YOU SAID:
I just leaving the house tomorrow
INTO JAPANESE
私は明日家を出るだけです
BACK INTO ENGLISH
I'm leaving home tomorrow
INTO JAPANESE
私は明日家を出ます
BACK INTO ENGLISH
i will leave home tomorrow
INTO JAPANESE
私は明日家を出ます
BACK INTO ENGLISH
i will leave home tomorrow
That didn't even make that much sense in English.
