My Story: It was July the 13th when i had all my relatives and friends over my house for a dinner. While we were eating, I heard a knock on the door. I told my younger sister to open the door as it might be one of her friends. She told me that there wasn't any knock. I was frustrated and went to open the door and eventually there wasn't any one there. I went back on to my seat and everyone look at me and was wondering what was happened. I never knew who knocked on the door till now.
