YOU SAID:
if i were a zombie i would never eat your brain
INTO JAPANESE
私がゾンビだったら私はあなたの脳を食べない
BACK INTO ENGLISH
I will not eat your brain if I am a zombie
INTO JAPANESE
私はゾンビであれば私はあなたの脳を食べません
BACK INTO ENGLISH
I will not eat your brain if I am a zombie
That didn't even make that much sense in English.
