YOU SAID:
I look at myself using a mirror
INTO JAPANESE
鏡を使って自分を見ている
BACK INTO ENGLISH
I am watching myself with a mirror
INTO JAPANESE
私は鏡で自分を見ています
BACK INTO ENGLISH
I am looking at myself in a mirror
INTO JAPANESE
私は鏡で自分を見ています
BACK INTO ENGLISH
I am looking at myself in a mirror
That didn't even make that much sense in English.
