YOU SAID:
yesterday i brainfarted and forgot my name
INTO JAPANESE
昨日私は頭を悩まし、私の名前を忘れてしまった
BACK INTO ENGLISH
Yesterday I bothered my head and forgot my name
INTO JAPANESE
昨日私は頭を悩まして、私の名前を忘れた
BACK INTO ENGLISH
Yesterday I bothered my head and forgot my name
That didn't even make that much sense in English.
