A Feat

All my stuff was in that locker. I was about to lock it when a woman walked in and told me that the lock was broken. She suggested that I move all my stuff to another locker like she had done one hour before.
I checked the lock and thought I fixed a similar locker before. I believed this lock could be fixed, too. However, the woman kept pushing me to change to another locker. Her persistence shook my faith.
I was a person without an opinion when others made suggestions. However, I was too lazy to move the stuff. It was far more complicated than fixing a lock, so I twisted the lock a few times and it was fixed.
My mind sent me the strongest signal, “You can fix the lock.” This time I did not blow the signal off and I succeeded.
“Trust yourself” was not just a saying to me anymore.

("an aunt" sounds a little strange, so I replaced it with "a woman")
