YOU SAID:
The woods are lovely, dark and deep. But I have promises to keep, And miles to go before I sleep
INTO JAPANESE
森の中は、素敵な暗いと深いです。約束を守るとマイル眠る前に
BACK INTO ENGLISH
In the woods are lovely dark and deep. Promise to keep miles before going to sleep
That didn't even make that much sense in English.
