YOU SAID:
A potatoe flew around my room before you came
INTO JAPANESE
あなたが来る前にポテトーが私の部屋の周りを飛んできた
BACK INTO ENGLISH
Potatoes flew around my room before you came
INTO JAPANESE
あなたが来る前にジャガイモが私の部屋の周りを飛んできた
BACK INTO ENGLISH
Potatoes flew around my room before you came
That didn't even make that much sense in English.
