YOU SAID:
my mum slapped me this morning
INTO JAPANESE
私のお母さんは今朝私を叩いた
BACK INTO ENGLISH
My mother hit me this morning
INTO JAPANESE
私の母は今朝私を打つ
BACK INTO ENGLISH
My mother hits me this morning
INTO JAPANESE
私の母は今朝私を打つ
BACK INTO ENGLISH
My mother hits me this morning
That didn't even make that much sense in English.
