One night my parents went outside for a dinner party and I was alone at home So I decided to watch a horror movie it was 9:00pm and I was eating popcorn everything was fine until some noise came from the corridor I went there and I saw someone was knocking the door aggressively I was shocked and scared that my parents never came that much early from a dinner party and if they came that much early then they would never knock the door that way. Now what should I do? Should I open the door to see who is there or run and hide under the bed?
