YOU SAID:
im poping out of class today for an appointment
INTO JAPANESE
私は今日、約束のためにクラスを飛び出します
BACK INTO ENGLISH
I'm out of class today for a promise
INTO JAPANESE
今日は約束を破った
BACK INTO ENGLISH
I broke my promise today
INTO JAPANESE
今日は約束を破った
BACK INTO ENGLISH
I broke my promise today
That didn't even make that much sense in English.
