YOU SAID:
I have school tomorrow and I am sad
INTO JAPANESE
明日は学校があり、悲しいです
BACK INTO ENGLISH
I'm sad because there is a school tomorrow
INTO JAPANESE
明日学校があるので悲しいです
BACK INTO ENGLISH
I'm sad because I have a school tomorrow
INTO JAPANESE
明日学校があるので悲しいです
BACK INTO ENGLISH
I'm sad because I have a school tomorrow
That didn't even make that much sense in English.
