YOU SAID:
I run down on him 'fore I have a running me
INTO JAPANESE
私は私を走らせる前に彼に駆け寄る
BACK INTO ENGLISH
I run up to him before running me
INTO JAPANESE
私は走る前に彼に駆け寄る
BACK INTO ENGLISH
I run up to him before running
INTO JAPANESE
私は走る前に彼に駆け寄る
BACK INTO ENGLISH
I run up to him before running
That didn't even make that much sense in English.
