YOU SAID:
My pet bird got sold to the circus after biting my sister
INTO JAPANESE
私のペットの鳥は姉に噛まれてサーカスに売られた
BACK INTO ENGLISH
My pet bird was bitten by my sister and sold to the circus
INTO JAPANESE
私のペットの鳥は妹に噛まれてサーカスに売られた
BACK INTO ENGLISH
My pet bird was bitten by my sister and sold to the circus
That didn't even make that much sense in English.
