YOU SAID:
My mother ate my potato so my dog ate her
INTO JAPANESE
母は私のジャガイモを食べたので、私の犬は彼女を食べました
BACK INTO ENGLISH
My dog ate her because my mother ate my potato
INTO JAPANESE
母は私のジャガイモを食べたので、私の犬は彼女を食べました
BACK INTO ENGLISH
My dog ate her because my mother ate my potato
That didn't even make that much sense in English.
